Which is a y-intercept of the graphed function​

Well, a y-intercept is a the point on a graph where the x value equals 0, because the point sits exactly on the y-axis. In this case, the y-intercept would be (0, -9).

(0,-9)

Step-by-step explanation:

The y intercept is where the graph crosses the y axis ( where x =0)

The y intercept is

-9

(0,-9)

40 minutes

step-by-step explanation:

add the time and multiply by 2

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
