Question

Slope intercept form of Line (-9,3), (-5,7)

Answer 1

y = x + 12

Explanation:

(-9, 3), (-5, 7)

(x₁, y₁) (x₂, y₂)

y₂ - y₁ 7 - 3 4 4

m = ------------ = ------------- = ----------- = --------- = 1

x₂ - x₁ -5 - (-9) -5 + 9 4

y - y₁ = m(x - x₁)

y - 3 = 1(x - (-9)

y - 3 = 1(x + 9)

y - 3 = x + 9

+3 +3

-------------------------------

y = x + 12

I hope this helps!
