Question

Is y = 2/3x - 7 proportional or not?

Answer 1

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.
