Answer:

Option C. the volume of water in the tank is decreasing by 0.4L per hour

Step-by-step explanation:

step 1

Find the slope

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

$A(2,8)\ B(7,6)$

Substitute the values

$m=\frac{6-8}{7-2}$

$m=\frac{-2}{5}=-0.40\frac{liters}{hour}$

The slope is negative

is decreasing

That means------> the volume of water in the tank is decreasing by 0.4L per hour
