Question

A limo compay charges a $75 fee to make a reservation and then $3 per mile. What is the equation of this story in slope intercept form

Answer 1

• y = 3x + 75

Explanation:

Slope-intercept form:

• y = mx + b, where m- slope, b - y-intercept

The flat rate charge is the y-intercept:

• b = 75

The charge per mile is the slope:

• m = 3

Substitute the values to get the equation:

• y = 3x + 75

Answer 2

Multiply the amount per mile by number of miles, use x for the number of miles. Then add the fee to that to gets the total (y).

Answer: y = 3x + 75
