What is the slope of the line passing through the points (2, - 5) and (4, 1)?

3

Step-by-step explanation:

Slope = y2-y1 / x2-x1

          = 1- (-5) / 4-2

          = 1 + 5 / 2

          = 6 /2

          = 3

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
