Complete the equation of the line through (-9,7) and (-6,-3).

Answer 1

We need to find the slope based on the given points: (-9, 7) and (-6, -3)

m = Δy/Δx = (-3 - 7) / (-6 - (-9)) = -10/3

Set up the point-slope form. Choose either of the points to plug in to.

y - y₀ = m(x - x₀)

y - 7 = (-10/3)(x - (-9))

y - 7 = (-10/3)x - 30

y = (-10/3)x - 23

y - (-3) = (-10/3)(x - (-6))

y + 3 = (-10/3)x - 20

y = (-10/3)x - 23
