Question

Write an equation for the line that passes through (8,6) and (-8,2)​

Answer 1

y=1/4x+4

Explanation:

1. y1-y2/x1-x2 = slope

6-2/8--8

6-2/8+8

4/16

1/4 = slope

2. y=mx+b (m=slope and b= y-intercept)

y=1/4x+b

(plug in one set of coordinates for x and y)

6=1/4(8)+b

6=2+b

6-2=b

4=b

(plug in 4 as y-intercept)

y=1/4x+4
