Which is the slope of the line represented by the equation 4x – y=8? A.4
B.2
C.-4
D.-8

-4

Step-by-step explanation:

Thats what i would think because i think you have to subtract both sides of the equation, and any line can be graphed using 2 points. So maybe just select 2 x values, and put/plug them into the equation to find the corresponding y values. Then graph the line using the slope and the y-intercept, or the points.

Slope: -4

y-intercept: 8

I hope i got it right :>

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
