On a coordinate plane, a line goes through (0, 0) and (8, 6). A triangle has a rise of 3 and run of 4. A larger triangle has a rise of y and run of x. Use the similar triangles on the coordinate plane to determine the equation for the given line. Y = three-fourths x y = four-thirds x y = 4x + 3 y = 3x + 4

plz yuo

step-by-step explanation:

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
