Question

11. The table shows the distance, y, a car can travel in feet in x seconds. Speed or Car Time, x (seconds) 5 10 Distance, y (feet) 700 1,400 2,100 2,800 3,500 15 20 25 Based on the information in the table, which equation can be used to model the relationship between x and y? A. y = 140x B.y = 5x C. y = x + 140 D. y = x + 5

Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

y = distance

x = time

equation = ?

Step 02:

y = k x

if y = 700ft , x = 5 seconds

700 = k * 5

700 /5 = k

140 = k

y = 140 x

The answer is:

y = 140 x
