Answer:
A. y = -8x -5
Step-by-step explanation:
You will notice that when x increases from 2 to 5, y decreases from -21 to a number that is more negative. Thus only the first two answer choices are possibilities, since the others have a positive coefficient for x.
Trying the first given point in the first answer choice, we see that it works:
-21 = -8·2 -5
so, that is the equation we're looking for.
y = -8x -5
