Find the equation for the line that passes through the point (-4,2) and that is perpendicular to the line with the equation x=-3

y = 2

Step-by-step explanation:

x = - 3 is the equation of a vertical line parallel to the y- axis.

Thus a perpendicular line must be a horizontal line parallel to the x- axis with equation

y = c

where c is the value of the y- coordinates the line passes through.

The line passes through (- 4, 2) with y- coordinate 2, thus

y = 2 ← equation of perpendicular line

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
