Question

Compare the y-intercepts and rates of change of the following items.

A.
The items have different y-intercepts and different rates of change.

B.
The y-intercepts are the same, but the rates of change are different.

C.
The rates of change are the same, but the y-intercepts are different.

D.
The items have the same y-intercept and the same rate of change.

Answer 1

Explanation:

I just took it

Answer 2

D. They have the same slope ( rate of change) and the same y-intercept.

Explanation:

I y = 1.2x + 0.4.

II The slope is (10-4)/(8-3) = 6/5= 1.2.

Its equation is

y - 4 = (1.2)(x - 3)

y = 1.2x - 3.6 + 4

y = 1.2x + 0.4.
