Hello, d is the distance (total distance) an t the time (seconds of the timer).
So, we have that the total distance after 2 seconds is 35.
So put 35 as d...2 is the time so put 2 as t.
Write the equation as slope-intercet form d = mt + q
35 = 2m + b
5 is the d-intercept and the known term because the car travels 5 feet after the timer starts.
Solve it as a normal equation...
35 = 2m + 5
35 - 5 = 2m
30 = 2m
m = 30/2 = 15
Rewrite it as slope-intercept form...
d = 15t + 5
If we have to find the distance after 10 seconds, substitute 10 to t
d = 15(10) + 5
d = 150 + 5 = 155 feet
