Write an equation in point-slope form for the line that passes through each point with the given slope (-1,-2) m= 3

Vedmedyk [2.9K]

Answer:

Step-by-step explanation:

The Point-Slope form of equation of a line with slope of "m" and passing through point (x₁, y₁) is: y - y₁ = m(x - x₁)

m = 3

x₁ = -1

y₁ = -2

Therefore the equation:

y - (-2) = 3(x - (-1))
