An "equation has a solution of (2, 13)" means that if we substitute x with 2 in the equation y = -3x + 7, we should get y equal to 13. Let's test it by substituting x = 2 into the equation:
y = -3(2) + 7
y = -6 + 7
y = 1
The value we obtain for y is 1, not 13. Therefore, the coordinates (2, 13) do not satisfy the equation y = -3x + 7; thus, (2, 13) is not a solution to the equation, making Dr. Ellison's statement incorrect.
