I need help please it’s a test.

first image -2.4/3, second image the x intercept is 28, and it represents the time it takes to totally empty the pool

Step-by-step explanation:

the rate of change, or slope, of an equation is the change in y over the change in x. 11-13.4 = -2.4 and 5-2 =3

the x intercept is the x value when y = 0, so 28 in this case. the question is graphing the total volume of a pool and how long it takes to empty it, so when the pool has no water left in it then that's how long it takes to empty
