Question

PLZ HALP MEH. I suck at math. There's a picture to show you the question.

Answer 1

The solution to what you put down is 1,3

Answer 2

The equation is y=2x+1 because the slope is 2 and the y-intercept is 1

For part B I can't graph it for you but I can try to help. Since the y-intercept is 4, one of the points is (0,4). Then to find other points, since the slope is 1/2, you move up one box and over two to get another points. So one more point is (2,5). Then connect the points with a line.

I think C just means to write out the equations so you can solve them in the next part. To solve them you can do elimination.

(y=2x+1)-(y=1/2x+4)
0=3/2x-3
3=3/2x
x=2 (multiply 3 by 2/3)
