4-2 Writing Equations in Slope-Intercept Form
( 2, 4), (2, 4)
Find the slope of the line containing the given points.
Use the slope and either of the two points to find the y-intercept.
Write the equation in slope-intercept form.
Greg is driving a remote control car at a constant speed. He starts the timer when the car is 5
feet away. After 2 seconds the car is 35 feet away.
Write a linear equation to find the distance d of the car from Greg.
Estimate the distance the car has traveled after 10 seconds.
a. Let t be the number of seconds after the timer starts. Let d be the distance traveled by the car.
The d-intercept is 5, because the car has traveled that far when the time starts at 0. Use the slope-intercept form to
find the slope, which is distance divided by time, or the speed of the car.
Write the equation in slope-intercept form with t as x and d as y.

The distance of the car from Greg can be represented by the linear equation d = 15t + 5.
b. Solve for d when t = 10.
