Solving systems of equations by graphing is a method of solving a system of two linear equations. Solving systems of equations by graphing follows a specific procedure to simplify the solutions. The first thing you should do when solving systems of equations by graphing is to graph each equation. When graphing equations you start with the y-intercept, or where the line crosses the y-axis. Then, you use the slope to plot the next points and graph the lines. The slope is the increase divided by the flow for the equation. The last step in solving systems of equations by graphing is to find the intersection point between the two lines.

Solving systems of equations by graphing is a way to simplify a set of two mathematical statements. The first thing you should do when solving systems of equations by graphing is to graph both mathematical statements. The easiest way to graph equations is in slope-intercept form because it gives you the y-intercept and the slope. The last part when solving systems of equations by graphing is to find where the lines cross on the graph because that is your solution.

Lesson 5 1 Solving Systems By Graphing
The first problem in our system of solving equations by graphing worksheet gives us y equals 2x minus 3 and then y equals negative 3x plus 2. We look for the solution of these two equations and the system they form. This means that we are looking for the point of intersection of two equations. For example, this is not the answer, but for example if we have our graph here and we had an equation that was like this and another equation that when you counted it was like this, the solution to the equation is the intersection. of . It is the point that satisfies both equations, which will be the point that crosses the two equations.
To solve systems of equations by graphing, you must graph both equations and then you must find the intersection point on the graph, and the coordinate will be your answer. To find the point of intersection we first have to graph both equations, the equations are written in slope-intercept form, which means you can use the slope and you can use the y-intercept to graph them.
In the case of the first one we know that the slope-intercept form y is equal to MX plus B, we know that M is the slope because it always lies with x and we know that B is the y-intercept. In the case of this equation, M which is the slope is 2 and then B which is the y-intercept is negative 3, and we will graph the equation in red. We have a y-intercept of negative 3 and a slope of 2. We’re going to go down to negative 3 for the y-intercept, which is right here, and then we follow the slope, which is 2, or the increase in flow over, which is 1 over 2. You go to 2 and then to 1. We’ll start at our y-intercept and we’ll go 2 over 1 I’ll go over 1 over 2 and so on.

Then we have to do the same thing for y equals negative 3x plus two. We have to find the slope and y-intercept and then graph it. In this case, the slope is negative 3 and the y-intercept is positive 2. We’re going to start with our y-intercept which is 2. We’re going to go up to 2 and then we’re going to graph our slope which is negative 3. Negative 3 over 1 or down 3 and then over 1. We’ll start at our point, we’ll go down 1 2 3 over 1 down 1 2 3 over 1 and we’ll then graph when we have some points we can go ahead and add them up. This is our second equation in blue.
Now our system solution here is going to be the intersection point, which is right here. This is the only point that will be true for both equations or that will satisfy the system. The point here is x is 1 y is negative 1. Our solution to the system of equations is x is equal to 1 and y is equal to negative 1. And in coordinates it’s going to be 1 negative 1 and that’s the solution.
Number three on the Solving Systems by Graphing worksheet gives us our system which in this case is y equals 4x plus 3 and the second equation is y equals negative x minus 2. We have to do the same thing we did in the second problem . We’ll go ahead and find the slope and y-intercept for each equation. The slope for y is 4x plus 3 is 4 and the y-intercept is positive 3, and for the second equation we have y equals negative x minus 2. Our slope is even though it’s negative x, that’s like saying that It’s actually like saying negative 1x. It is not written but there is one. This is actually negative 1x and our y-intercept is negative two.

We are going to graph the next. I’m going to graph the first one in red. Our y-intercept for the first one is 3. We go to our y-axis and plot 3 and the slope is 4. We’re going up 4 and then up 1. We’re going to go 1 2 3 4 up. 1 over 4 over 1 would be right here you can also go back so we’ll go 1 2 3 4 down and then this way. You can go in the negative direction and then you can go ahead and graph the equation or draw our line.
I should say we’re going to do the same thing for the blue equation which is y is equal to negative x minus 2. We’re going to start with negative 2 which is our slope here is 1x. We will go down 1 this time and then up 1. We will go 1 over 1 down 1 over 1 down that goes in this direction and then you can always go back. You go up and left instead of down and right we will go that way. And once we have our points ready, we can go ahead and draw our line.
And once again to solve systems of equations by graphing you have to find the point of intersection between the equations. Our point of intersection is there. This is where the two lines intersect, in this case it would be negative 1 negative 1. X is negative 1 Y is negative 1. Solution X will be negative 1 Y will be negative 1 and solve in terms of coordinates. Negative 1 Negative 1.
