Point-slope form (-8,-1) and (-6,5)

Question

Complete the point slope equation of the line through (-8,-1) and (-6,5) use exact numbers

Answer 1

y - y₁ = m(x - x₁)

m = [5 - (-1)] / [-6 - (-8)] = 6/2 = 3

Use either point for x₁ and y₁ in the point slope equation:

y + 1 = 3(x + 8)

y - 5 = 3(x + 6)

These are equivalent.
