2. Write an equation in point-slope form to represent the amount charged, C, for m number of miles by the company in Charlotte.
To write an equation in point-slope form, we need a point on the line and the slope of the line. Let's say the company charges $x for every mile.
Let's assume that if the number of miles is 0, the amount charged is $20 (y-intercept). Therefore, we have the point (0, 20) on the line.
The slope of the line would be equal to the amount charged for each mile, which is x.
So, the equation in point-slope form representing the amount charged, C, for m number of miles by the company in Charlotte is:
C - 20 = x * m
