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?

m = 60

Step-by-step 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.
