Answer:
100x
Step-by-step explanation:
Answer:
-1
Step-by-step explanation:
Solve for y into y=mx+b
2x-2y=20
-2y=-2x+20
y=(-2x+20)/-2
y=x-10
the slope is m, so it’s 1
A line perpendicular to that would be -1
(12 2/3) divided by 8 = 19/12 or 1.58333333333333
This might be wrong but probably y= 0.5x ?
