Car moving at a constant speed passes a timing device at t=0. After 6 seconds, the car has traveled 564 ft. Write a linear function rule to model the distance in feet d the car has traveled any number of seconds t after passing the timing device.

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

answer: the slope is equal -1.
