Answer 1

Answer:

y = .5x +15

The graph is a line.

The slope is .5   and the y intercept is 15.  The flat fee is the y intercept and the cost per mile is the slope.

Step-by-step explanation:

The flat fee is the y intercept and the cost per mile is the slope

The total cost for the day is equal to the cost per mile * the number of miles driven plus the flat fee.  Let x be the number of miles driven and y be the total cost for the day.

We can use y = mx+b

y = .5x +15

When we graph, x must be greater than 0 because we cannot drive negative miles.

The slope is .5   and the y intercept is 15.  The flat fee is the y intercept and the cost per mile is the slope.

Answer 2

Answer:

A) y=.50x+15

B) The graph would be a line starting in the bottom left corner and rising to the upper right, the start of the y axis would be 1, as it represents the miles, and the start of the x axis would be 0.50, as it represents the amount of money charged per mile.

C) If you apply the formula y=mx+b to the equation, you will see that 0.50 is the slope, and 15 is the y-intercept.
