Question

If one point on a line is (6,-5) and the line's slope is - 8, find the y-intercept.

Answer 1

Answer: 43

Step-by-step explanation:

use point slope from

y-y1 = m(x-x1)

slope = m = -8

point = (x1,y1) = (6,-5)

so plug it in

y+5 = -8(x-6)

find the y intercept just means x = 0, so plug it in

y+5 = -8(0-6)

y = -8(-6)-5

y=43
