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

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

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

step-by-step explanation:

ok then what happened.
