Question

The equation y = -2.5x can be used to find y, the total money earned, if x, thenumber of hours worked. Which statement correctly describes the equation?A The equation is not proportional because the slope is negativeB. The equation is not proportional because the y-intercept is -2.5C. The equation is proportional because the y-intercept is zeroD. The equation is proportional because the slope is -2.5I8.5H

Answer 1

Answer:

D. The equation is proportional because the slope is -2.5

Explanations:

The number of hours worked = x

The total money earned = y

The equation is given as:

y = -2.5x

Note that:

A proportional relationship is of the form y = kx

Since y = -2.5x takes the form y = kx, k = -2.5, and the equatiion can be said to be proportional.
