Darnell has recorded the estimated value of his car each year since 2017. Let x=1 correspond to the year 2017. Find the slope-intercept form of the equation for the line that passes through the points representing the value of his car in 2017, (1,24,349), and the value of his car in 2021, (5,17,999). Round the slope to the nearest hundredth, if necessary. Year Value, $$ 2017 24,349 2018 22,200 2019 20,100 2020 19,100 2021 17,999

A car initially sold for $23,999. Its class life is 12 years, and the car depreciates by $750 each year. Express this as a linear function. Find the salvage value. Then, find the value after six years.

Using y=2-2x, plot the ordered pairs from the table. Then graph the function represented by the ordered pairs and tell whether the function in linear or nonlinear.

You are given a table of values for a linear function. For this table, find the missing value, a. a = y -2 10 a 14 41

The cost in dollars, y, to participate x days in a bike tour is a linear function. Lou’s bike tour is described by the equation y = 6x + 40. The cost of Mary’s bike tour is $120 for a 14-day bike tour. If both Lou and Mary take 14-day tours, whose bike tour costs less? *
