For positive x, y = 2x + 5. As x increases, y increases. Why is this not direct proportion?
Ay is greater than x
By is always positive
Cy/x is not constant
Dx and y both increase
Answer & Solution
Correct answer: C. y/x is not constant
The ratio is y/x = 2 + 5/x, which changes with x because of the fixed added amount.
