The function graphed shows the total cost of a gym membership for x months. select form the drop down menus to correctly identify the gym membership information provided by the graph:
(see image)

the slope is (15//10//1.5//1)
the slope represents
1: the total cost of the membership
2: the starting fee
3: the monthly cost of the membership
4: the number of months as a membership

the slope is 10 and the y intercept represents the monthly cost of the membership

if x decreases by 4 then y increases by 10

step-by-step explanation:

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
