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 \( x = 3 \):
\[ y = 0.75(3) - 1.5 \]
Calculating:
\[ y = 2.25 - 1.5 \] \[ y = 0.75 \]
Since the calculated \( y \) value equals the \( y \) value of the point \( (3, 0.75) \), the point is indeed on the graph.
Thus, the answer is 1 for yes.
