The constant is 3.
In mathematics, a constant term is a term in an algebraic expression that has a value that is constant or cannot change, because it does not contain any modifiable variables.
We have been given that on a coordinate plane a line with negative slope passes through points
and
. We are asked to find the rate of the change of the function.
We know that slope represents rate of change of function.
We will use slope formula to solve our given problem.

Let
and
.



Therefore, the rate of change of the given function is
.
Answer:
63.2
Step-by-step explanation:
90+26.6=116.8
