28. As part of a lesson on motion, students observed a cart rolling at a constant rate along a straight line. As shown in the chart below, they recorded the distance, y feet, of the cart from a reference point at 1-second intervals from t = 0 seconds to t = 5 seconds.

Which of the following equations represents this data?

Answer and Explanation

Your Answer is

Correct Answer is H

Explanation

It can be seen that the amount of change of y is fixed at 5. So the equation is a linear equation with slope 5. And when t=0, y=14, we can know that the intercept is 14. So the equation is y=5t+14. Therefore choose H.
