Question

Graph y=8.5xy=8.5xy, equals, 8, point, 5, x.

Answer 1

Answer:

• A, B, E

Step-by-step explanation:

Given equation

• y = 8.5x

Answer choices

A. The equation represents a proportional relationship.

• TRUE, it is in the form of y = kx

B. The unit rate of change of y with respect to x is 8.5

• TRUE, y = mx + b, the slope m = 8.5 is the rate of change

C. The slope of the line is 2/17

• False, the slope is 8.5

D. A change of 17 units in x results in a change of 2 units in y.

• False, a change of x = 17 results in 17*8.5 = 144.5 units in y

E. A change of 4 units in x results in a change of 34 units in y.

• TRUE, because 4*8.5 = 34
