Question

Which equation represents a proportional relationship?


y=−x

y=−5(x+1)

y=15x

y = 5x + 1

Answer 1

Answer:

1st and 3rd

Step-by-step explanation:

Because in these two equations there is constant like -1 in Ist and 15 in 3rd being multiplied by x. So these are in proportion

Answer 2

Step-by-step explanation:-

y = 15x is a direct proportion. when x gets bigger, y also gets bigger. y = 15/x would be an inverse proportion. when x gets bigger, y gets smaller.
