Question

Write the equation of the line that passes through (-3, -20) and (1, 4).

Answer 1

y=6x-2

Explanation:

first step: find the slope

equation to find slope: (y2-y1)/(x2-x1)

let x1, y1 be (-3, -20)

let x2, y2 be (1, 4)

(4 - (-20))/(1 - (-3)) = 24/4 = 6

plug in 6 and x,y to find b

4=(6)(1) + b

subtract 6 on both sides = -2=b

y=6x-2
