Question

Complete the equation of the line through
(-8,8) and (1,-10)
Use exact numbers.

Answer 1

y = -2x-8

Explanation:

1. (-8,8)

2. (1,-10)

first lets find the slope

m = y2-y1 / x2-x1

m = -10-8 / 1-(-8)

m = -18 / 9

m = -2

y = -2x+b

lets find b by plugging in point 2

-10 = -2(1)+b

-10 = -2+b

b = -8

our equation:

y = -2x-8
