Question

You are driving along the open highway on a cross-country road trip, cruising at a steady speed of 60 miles per hour. What is the slope of the line representing this relationship?

Answer 1

m = 60

Explanation:

The relation is the number of miles travelled/the number of hours, as the unit is miles/hr. In one hour, 60 miles is travelled, so that means that if we plug in the numbers, we get 60/1, or 60.

Answer 2

The slope is 60.

Explanation:

Let t=0. Then d= 60(0) = 0, so the point (0,0) lies on the line.

Now let's make t=1. Then d= 60(1) = 60, so the point (1,60) lies on the line.

I also did it on Khan and and it was correct.
