Does direct proportion need to have a slope of 1?

No, direct proportion does not necessarily need to have a slope of 1. A direct proportionality relationship means that as one variable increases, the other variable increases at a constant rate, which can be represented by the equation (y = kx), where (k) is a constant. If (k = 1), the slope will be 1, but any positive value of (k) will still represent a direct proportion, just with a steeper or shallower slope.
