To determine if the point (3, 0.75) is on the graph of the function \( y = 0.75x - 1.5 \), we can substitute \( x = 3 \) into the equation and see if the resulting \( y \) value equals 0.75.
Substituting \( x = 3 \):
\[ y = 0.75(3) - 1.5 \] \[ y = 2.25 - 1.5 \] \[ y = 0.75 \]
Since the calculated \( y \) value (0.75) matches the \( y \) value of the point (3, 0.75), we conclude that (3, 0.75) is indeed on the graph of the function.
So, the answer is 1 (yes).
