Answer to Problem 17CT
The equation of our line in slope-intercept form would be
Explanation of Solution
Given:
The table shows the number of televisions sold each month at a retail store.
Calculation:
First of all, we will find slope of line passing through points
Now we will substitute slope and coordinates of point
Therefore, the equation of our line in slope-intercept form would be
