Question

Solve the following system of equations by graphing.
y = –2x + 1
y = x – 2

Give me some time to get the graphs up :)

Answer 1

A-Graph1
B-Graph2
C-Graph3
D-Graph4

Answer 2

It's C. :)

First you look at the y-intercepts. for the first equation, the line passes through the y-axis at 1 unit up. And the next point follows the slope (2 units down, one to the right)
The second equation, the y-intercept is at 2 units down. And the next point goes up one and to the right one.
Hope this helps!!
