Answer:

15.D

16.A

Step-by-step explanation:

Hello There!

For 15

We can find the slope given two points by using the slope formula

[tex]slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

so given the two points (2,-3) and (-2,5)

we plug in the y values and x values into the formula

[tex]slope=\frac{5-(-3)}{-2-2} \\5-(-3)=8\\-2-2=-4\\slope=\frac{8}{-4}[/tex]

Finally we want to simplify

8/-4=-2

so we can conclude that the slope of a line that passes through the points (2,-3) and (-2,5) is -2 (D)

For 16

The y intercept is at (0,0) meaning that at 0 hours there was no water in the pool

So we can conclude that the pool was originally empty
