Slope Formula - (y² - y¹) / (x² - x¹)
(1, 7)
x¹ = 1
y¹ = 7
(-4, -8)
x² = -4
y² = -8
-8 - 7 = -15
-4 - 1 = -5
Simplify - -15/-5
-15/5 = -3
Your answer is -3.
Hope this Helps!!
multiply all terms in the second equation by 2 to get the coefficient on the y variable to be -6.

I believe the answer is the last option choice.
