Help! only find the equation of the line. urgent!

Step-by-step explanation:

Hey there!

Well let's start with slope,

The slope is 3x because the rise is 3 and the run is 1 so the slope is 3x.

Slope = 3

Now the y intercept is -4 because that's where the line touches the y axis.

Equation: y = 3x - 4

Hope this helps :)

ian gonna lie that is way to much

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
