Answer:
The average rate of change is equal to
Step-by-step explanation:
we have
-----> this is a linear direct variation
we know that
The rate of change of a linear variation is a constant
The rate of change of a linear variation is equal to the slope of the line
In this problem the slope of the line is equal to
therefore
The average rate of change is equal to
<u>Verify</u>
the average rate of change is equal to
In this problem we have
Substitute
Option C
<u>ANSWER: </u>
For the given equation slope is so the correct option is c.
<u>SOLUTION: </u>
Given, line equation is
We need to find the slope of the given equation.
Above given equation is in the form of slope intercept form, i.e. y = mx + c
Where m is the slope and c is the intercept made on axis by this line.
By comparing the given equation and the general form, we can conclude that, m = and c = -3
hence, for the given equation slope is . so the correct option is c.
