Dr Ellison says that the equation y = -3x + 7 has a solution of (2, 13) is dr Ellison right or wrong?

Question

A. Dr Ellison is right
B. More information is needed to answer this question
C. Dr Ellison is wrong

Answer 1

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.
