Answer:
Slope = 0.08 dollars per minutes.
Step-by-step explanation:
Carla pays $20 per month for her phone service, plus $0.08 for each long-distance minute used.
Therefore, if Carla talks for m minutes in the long-distance call, then the situation can be modeled by the equation
C = 20 + 0.08m ............ (1), where C is the total cost for her phone service per month.
Here, 20 is the fixed price and 0.08m is the variable price for her phone charges.
This equation (1) represents a straight line with y-intercept as 20 and the slope as 0.08, where m plotted along x-axis and C is plotted along the y-axis. (Answer)
