The correct response is:

No, because the graph of the equation does not pass through the origin and the ratio of y/x is not equivalent for each point on the line.

In a proportional relationship, the graph is a straight line that passes through the origin (0,0), and the ratio of \(y/x\) must be constant for all points. In this case, the equation \(y = \frac{3}{4}x - 5\) indicates that the line has a y-intercept of -5, which means it does not pass through the origin, thus indicating that the relationship is not proportional.
