Dr.Ellison say that the equation y=3x+7 has a solution of (3,-2). Is Dr. Ellison right or wrong?

To determine if Dr. Ellison is right or wrong, we can substitute the values (3,-2) into the equation y = 3x + 7:

y = 3x + 7
-2 = 3(3) + 7
-2 = 9 + 7
-2 = 16

Since -2 does not equal 16, we can conclude that Dr. Ellison is wrong. The equation y = 3x + 7 does not have a solution of (3,-2).
