Question

Which equation represents the line that passes through the points (–3, 7) and (9, –1)

Answer 1

Answer:

2x+3y-15 = 0

Step-by-step explanation:

equation of line passing through (x₁,y₁),(x₂,y₂) is

y-y₁ = m(x-x₁)

m = (y₂-y₁)/(x₂-x₁)

m = (-1-7)/(9+3) = -8/12 = -2/3

y-7 = -2/3 (x+3)

3y-21 = -2x-6

2x+3y-15 = 0
