Question

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

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

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

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

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

Answer 1

B

Explanation:

Equation of line II:

y-intercept = b = -1

y = mx + b

y = mx - 1

Plugin the point(2,0) in the above equation,

0 = 2m- 1

2m = 1

m = 1/2

Equation of line :

`y = (1)/(2)x - 1`

Both have same y-intercept and the same rate of change.
