Question

Y=-1/2x+1 and y=1/3+6

Answer 1

If your teacher taught rise over run, then for the graphs:

y=-1/2x+1
start at y intercept of 1, then down 1, right 2 all the way, same for the other side but reversed.

y= 1/3+6
start at y intercept of 6, then up 1, right 3 all the way, same for the other side but reversed.

One solution: (-6,4)

Answer 2

-1/2x+1=1/3x+6
X6
-3x+6=2x+36
5x=-30
X=6

-6/2+1=y
-2=y
