Let's assume
depth of pound over time is h cm
time in hours as t
We are given
At the beginning of a storm, a pond was 16 cm deep
so, we get
so,
we can use formula
the depth increased by 1.5 cm every hour for 8 h
so, we get
so, we can plug these values
and we get
now, we can draw graph
Graph:
Slope = (y1 - y2)/(x1 - x2)
Slope = (-2 - -5)/(-8 - 0)
Slope = (-2 +5)/(-8)
Slope = 3/-8
we conclude that when we evaluate in x = 7, the given expression is equal to 12.

How to evaluate the expression?</h3>
Here we have the expression:
6*(x - 5)
Which represents the product of 6 and the sum between x and negative 5.
We want to evaluate it in x = 7, that means just replacing the variable in the given expression by the number 7, and then solving the expression.
Let's do that:
6*(7 - 5) = 6*(2) = 12
In this way, we conclude that when we evaluate in x = 7, the given expression is equal to 12.
