Question

A line with a slope of 3 passes through the point (-1, 2).

Write an equation for this line in point-slope form.

Answer 1

Explanation:

Slope = m = 3

(x₁ , y₁) = (-1 , 2)

Point slope form: y - y₁ = m(x - x₁)

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

y - 2 = 3(x + 1)

y - 2 = 3*x + 3*1

y - 2 = 3x + 3

y = 3x + 3 + 2

y = 3x + 5
