Which graph shows a car traveling at 50 miles per hour?

The graph on the bottom left shows a car traveling 50 miles per hour

The answer to your question would be the third graph to your left

Step-by-step explanation: because when you calculate the rate of change from these points:

(50,1)

(100,2)

(150,3)

(200,4)

The rate of change would be 50 miles/ km per hour

Finding the slope formula:

And when you take any two points from the graph, for example: (50,1) and (200,4), it would look like this:

one that is bigger than 3 1/2
