Given a line whose slope, m, is -3, and passes through point (-1,7),the graph will: A: go up to the left and cross the y-axis at 7
B: go down to the left and cross the y-axis at 4
C: go up to the right and cross the y-axis at 7
D: go down to the right, and cross the y-axis at 4

$12. that is my answer.

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

mrb
