The statement that is NOT true about a direct proportion is: “Its graph must have a slope of 1.”
Explanation: A direct proportion means that as one variable increases, the other variable increases at a constant rate. This results in a linear graph that passes through the origin and has a constant slope. However, the slope does not have to be 1; it can be any positive constant. For example, if y is directly proportional to x with a constant of proportionality k (y = kx), the slope of the graph would be k, which could be any non-zero number.
