y=100x−600

A.) (-5.5, -61)

B.) (-55, -6100)

C.) (-5.5, -610)

D.) (-55, -610)

-2 is the right

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
