Question

Write an equation in slope intercept form that describes a line with a slope of 3 and containing the point (5,-1)

Answer 1

y = 3x - 16

Explanation:

Equation of line with a given slope of a and containing a given point (x₀, y₀):

y - y₀ = a(x - x₀)

a = 3, x₀ = 5, y₀ = -1

So:

y - (-1) = 3(x - 5)

y = 3x - 15 - 1

y = 3x - 16
