Slope intercept form of (8, 2); slope -3/4 (y=m*x+b is the formula)

use point slope

y - y1 = m (x - x1)

y - 2 = -3/4 (x - 8)

y - 2 = -3/4x - 24/8

y - 2 = -3/4x - 3

+2                 + 2

     y = -3/4x - 1

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
