Answer:
y = -2x
Step-by-step explanation:
First you can find the difference between the two points to find the slope.
0, 4
- 1, 2
-1, 2
Now divide: y/x = 2/-1 = -2
Slope = -2
Formula: y=mx+b
Plug in the points for the variables.
2 = -2(1) + b
2 = -2 + b
Subtract 2 from both sides to get 0 = b so this line is proportional.
Hope that helps and have a great day!
