Question

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