Question

An equipment rental company charges $40 per day to rent a trench digger. A construction crew rented a trench digger for 6 days and paid 270. Write a linear equation in slope-intercept form that represents the total cost to rent the trench digger as a function of the number of days.

What should x and y equal, what is the y-intercept, and what is the equation


BTW THIS IS 40 POINTS

Answer 1

• y = 40x + 30

Explanation:

$40 per day represents the slope

Finding the y-intercept:

• 270 - 6*40 = 30

The function is then:

• y = 40x + 30
