What is the slope of the line that contains the point -6,-7 and -6,2

Slope is undefined.

Step-by-step explanation:

slope is defined as the steepness of a line.It is also called gradient.

It is denoted by m.

It is ratio of change in y to change in x.

m=Δy/Δx=

From question statement, we observe that

putting above values in formula to find slope,we get

m=2-(-7)/-6-(-6)

m=2+7/-6+6

m=5/0= undefined.

The slope of vertical line is undefined.

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
