Answer:
D. y = –2x – 7
Step-by-step explanation:
First, find the <em>rate</em><em> </em><em>of change</em><em> </em>[<em>slope</em>]:
-y₁ + y₂\-x₁ + x₂ = m
In this case, the y-intercept of [0, -7] is ALREADY given to you, so we would not have to go further in this case.

Step-by-step explanation:
Answer:
See below.
Step-by-step explanation:
4)
So we have the expression:
We can use the power of a product property, where:
So:
For the left, -6 squared is the same as -6 times -6. This equals positive 36.
For the right, we can use the power of a power property. The property says that:
So:
So, all together, we have:
6)
We have the expression:
First, note that anything to the zeroth power (except for 0) is 1, thus, x^0 is also 1. Simplify:
And that's the simplest we can do :)
Notes for 6)
We <em>can</em> put the x^4 to the numerator. Recall that when you put an exponent to opposite side, you put a negative. In other words:
And vice versa:
So, we can write the above as:
However, traditionally, we want only positive exponents, so this wouldn't be correct.
