Hi there! The answer is -2.
We can find the slope of a formula by using the following formula:

x2 and y2 don't mean squared, but the x and y coordinate of our second point.
First we need to find two points on the line. Ijn this particular case we have (-3, 3) and (1, -5). Now we can fill in the formula.

Therefore, the third answer is correct.
~ Hope this helps you!

Answer:
990
Step-by-step explanation:
99+88+77+66+55+44+33+22+11+11+22+33+44+55+66+77+88+99=990
Dependent variable is dependent on the independent variable
m, because the amount of tread lost depends on how many miles you traveled
it's not, the amount of miles depends on how much tread you lost
m is indepdent
