Asked Apr 17, 2019

Consider the equation C space equals space 0.01 m space plus space 35, where C is the cost in dollars of a cell phone plan for month and m is the number of minutes used in one month. Explain the meaning of the slope and of the y-intercept in this equation.

Step 1

To determine and interpret the slope and the intercept in the given word problem

Step 2

In the standard equation of the line y=mx+c, in the coordinate plane, m, the slope represents the increase per unit and c , the intercept represents the value of y when x is 0.

Step 3

In this problem, the x-axis represents the minutes ...
