The set of ordered pairs (1,8.50), (3,25.50), (5,42.50), (6,51), (7,59.50) represents the cost of tickets for the school play for different numbers of tickets. The input represents the number of tickets and the output represents the total cost. Is the cost a function of the number of tickets?

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.

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
