To determine whether Dr. Ellison is right or wrong, we need to check if the point (2, 13) satisfies the equation \( y = -3x + 7 \).
Substituting \( x = 2 \) into the equation:
\[ y = -3(2) + 7 \] \[ y = -6 + 7 \] \[ y = 1 \]
The equation gives us \( y = 1 \) when \( x = 2 \), not \( y = 13 \).
Since (2, 13) does not satisfy the equation, Dr. Ellison is wrong.
The answer is:
C. Dr Ellison is wrong.
