Answer to Problem 6PPS
Explanation of Solution
Given information:
The table shows the total revenue of all of Central High School’s plays in recent school years.
Use two ordered pairs to write a prediction equation.
Calculation:
The objective is to consider two points write a prediction equation.
Let, the two points be
At the first slope of the line.
So, the formula to find the slope of the line is given below.
After that consider the first point and the slope to find the equation of the line in slope intercept form.
Hence, the equation is
c.
Use your prediction equation to predict the missing value.
