The equation C = 0.20x + 50 gives the cost C in dollars for renting a truck and
driving it x miles. This equation is in the form y = mx + b.
Identity the slope and write a sentence to describe the meaning of the slope.


  1. Answer:

    0.20 dollars/mile

    Step-by-step explanation:

    The slope actually has units. It has the meaning of 20 cents per mile. The units are cents per mile.

    But it can also be 0.20 dollars/mile which is probably the way you should interpret it in a math class. That way it matches the units of the 50 which is for certain in dollars.
