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:
Option D...
Step-by-step explanation:
Need to proportional ..which leads only the rate of increase per increasing values ....
For eg.
x=2y
While giving values to y we have ..
y=1 =>x=2
y=2 =>x=4
. . . .
. . . .
That the constant rate of increase will leads a straight path ....
No need to from or at origin ie., (0,0)
The first one.... y=$21x-$180
Hope this helps!!
