Dr. Ellison says that the equation y = -3x + 7 has a solution of (2, 13). Is Dr. Ellison right or wrong? (1 point) Responses Dr. Ellison is right. Dr. Ellison is right. More information is needed to answer this question. More information is needed to answer this question

Answer 1

To determine if Dr. Ellison is right, we need to check if the point (2, 13) is indeed a solution to the equation \( y = -3x + 7 \).

1. Substitute \( x = 2 \) into the equation: \[ y = -3(2) + 7 \] \[ y = -6 + 7 \] \[ y = 1 \]

2. The calculated value of \( y \) is 1. The point (2, 13) has a \( y \)-coordinate of 13, not 1.

Since the \( y \)-value we calculated (1) is not equal to the \( y \)-value of the point (13), Dr. Ellison is wrong.

So, the correct response is: Dr. Ellison is wrong.
