Answer:
y=-4x+2
Explanation:
1) Find the slope, choose two values (I'll use (1,-2), (2,-6))
Apply the slope formula,
(first y value - second y value)/(first x value - second x value)
(-2+6)/(1-2)=4/-1=-4
2) Plug it in, we need to find the y-intercept now
y=mx+b (m=slope, b=y intercept)
-2=-4 times 1 +b
-2=-4+b
2=b
3)Voila
y=-4x+2
