Answer: No, it is not a direct proportion equation

Step-by-step explanation:

Direct proportions are always in the form
y = kx where k is any nonzero real number. So for example, we could have the equation
y = 9x. The y intercept of any direct proportion is always zero. Visually, such equations will go through the origin.

Something like
y = (2)/(3)x-7 has a y intercept of -7 and it doesn't fit the form
y = kx, so it's not a direct proportion equation.
