What is the slope of the line through points -6,6 and 4,-7

-13/10, (-13/10) However your teacher wants you to write it y= -13, x=10

Step-by-step explanation:

Remember, slope is (y,x)

My teacher taught me rise (y) over run (x) so there ya go if you need to remember.

The equation is y2-y1 over x2-x1

In this case,

y = -7 - 6 = -13.

x= 4 - -6, aka 4+6 = 10

Put it together, you get -13/10

The line is going down going to the right,

Hope I helped!

it should be a and d. lmk if i'm wrong xd

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
