Using it's formula, the average rates of change are given as follows:
a) 30 meters per second.
b) -10 meters per second.
<h3>What is the average rate of change of a function?</h3>The average rate of change of a function is given by the <u>change in the output divided by the change in the input.</u> Hence, over an interval [a,b], the rate is given by the following equation:
For item a, taking the data from the table, we have that:
- f(0) = 0.
- f(4.6) = 138.
Hence the rate is given as follows:
r = (138 - 0)/(4.6 - 0) = 30 meters per second.
For item b, taking the data from the table, we have that:
- f(9.2) = 23.
- f(11.5) = 0.
Hence the rate is given as follows:
r = (0 - 23)/(11.5 - 9.2) = -10 meters per second.

Graph using slope and the y intercept
So y=x+5
You would plot the y intercept (0,5) and then go up 1 and to the right 1
The next graph plot y intercept (0,-1) and then go down 2 and to the right 1
And should look like the image
And your solution should be (-2,3) which is option c

Answer:
<em>The equation will be: </em>
Step-by-step explanation:
The number of student tickets that were sold
and the number of other tickets that were sold
Student tickets cost $3 a piece and tickets for everyone else cost $5 each.
So, <u>the total cost of</u> <u>student tickets</u>
and <u>the total cost of</u>
<u>other tickets</u>
Given that, the drama club sold <u>total $779 worth of tickets</u>.
So, the equation will be:
