Answer:
I'm not 100% sure but I'm pretty sure you are correct
Answer:
or 
Step-by-step explanation:
The equation of a line is
, with
being the slope and
being the y-intercept.
We can see on the graph that the y-intercept, where the line crosses or touches the y-axis, is 100. So, our new equation is
.
Now we have to find the slope. Let's pick a point that's clearly on the graph. Perhaps (3, 150). And then we'll take the y-intercept point for convenience, (0, 100).
Then, we'll use
to find the slope.
Let's substitute in our points.

Simplify.

Now, we can leave the slope like that or turn it into a mixed number. As a mixed number, your slope is
.
We'll put that in our equation for a line and...bam!

Answer: Choice F) 1</h3>
=============================================
Explanation:
x^2+8x+7 factors to (x+1)(x+7)
x^2+4x-21 factors to (x-3)(x+7)
Therefore, the numerator (x^2+8x+7)(x-3) updates to (x+1)(x+7)(x-3)
The denominator (x^2+4x-21)(x+1) updates to (x-3)(x+7)(x+1)
We have three pairs of terms that will cancel between the numerator and denominator. The (x+1) terms pair up and cancel out, so do the (x+7) terms and also the (x-3) terms as well. Everything cancels out. The only thing left is 1 because x/x = 1 where x is nonzero. We can have a more complicated expression replace x to get the same basic idea. This is what I mean by "canceling".
