Question

Find equation with points (-3,-8) and (1, 16)

Answer 1

The equation of the line is y = 6x + 10.

Explanation:

(-3,-8) (1 ,16)

x1, y1. x2,y2

Gradient(m) = (y2 - y1)/(x2 - x1)

= (16 - (-8))/(1 - (-3))

= 24/4 = 6

Equation of a line is given as:

(y - y1) = m(x - x1)

y - (-8) = 6(x - (-3))

y + 8 = 6x + 18

y = 6x + 10
