Answer:

4i^2 - 36

Step-by-step explanation:

(2i * -6) = -12i

(2i * 6) = 12i

(-6 * 6) = -36

combine like terms

GenaCL600 [577]

The slope or incline is -5

Step-by-step explanation:

rewrite to get the form

y = ...

x - 5y = -10

- 5y = -10 -x

divide left and right if the = sign by -5 gives:

(-5/-5)y = (-1/-5)x + (-10/-5)

y = 1/5x +2

So the incline is 1/5

a perpendicular line has an incline of -1 *5/1 = -5

The slope or incline is -5
