To determine if the point (2, 9) makes the equation \( y = x - 7 \) true, we can substitute \( x = 2 \) into the equation and see if we get \( y = 9 \).
\[
y = x - 7
\]
Substituting \( x = 2 \):
\[
y = 2 - 7 = -5
\]
Since \( -5 \) is not equal to \( 9 \), the point (2, 9) does not satisfy the equation \( y = x - 7 \).
Therefore, (2, 9) does not make the equation true.
