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!
They are 1, 2 and 3.
Hope that helped ^^
