Graph the system of equations.

{8x+8y=64
2x−2y=−4

We can use the x- and y-intercepts to graph. The x-intercept of the first equation is 8, and the y-intercept is 8. The x-intercept of the second equation is -2, and the y-intercept is 2.

x-intercepts are where the data crosses the x-axis. At every one of these points, the y-coordinate will be 0; therefore we can substitute 0 for y and solve to get the value of the x-intercept.

For the first equation, we would have

8x+8(0)=64

8x=64.

Divide both sides by 8:

8x/8 = 64/8

x=8.

For the second equation,

2x-2(0)=-4

2x=-4.

Divide both sides by 2:

2x/2 = -4/2

x=-2.

y-intercepts are where the data crosses the y-axis. At every one of these points, the x-coordinate will be 0; therefore we can substitute 0 for x and solve to get the value of the y-intercept.

For the first equation,

8(0)+8y=64

8y=64.

Divide both sides by 8:

8y/8 = 64/8

y=8.

For the second equation,

2(0)-2y=-4

-2y=-4.

Divide both sides by -2:

-2y/-2 = -4/-2

y=2.

Plot these points for both equations and connect them to draw the line.

question:

could we have options?

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.
