The graph shows the distance y (in miles) that a bus travels in x hours. Find and interpret the slope of the line. a) Find the slope of the line b) What is the speed of the bus? (mph)

The slope and speed of displayed by the graph is :

The slope of the line is the ratio of the rise and the run.

The slope = (Rise / Run) = (60 / 1) = 60

The slope means that the distance moved per hour by the bus during the trip is 60 miles

The speed is the distance moved per hour

The speed can be calculated thus :

Therefore, the slope is 60 and the speed is 60 mph.

a) 60

b) 60 mph

Step-by-step explanation:

(a)

Let :-

x¹ = 1

x² = 2

y¹ = 60

y² = 120

Slope of a line =

where &

So , putting all the values in the formula gives :-

(b)

In a distance - time graph , slope represents the speed .

In the first bit , we found the value of slope. So,

Speed of the bus = 60 mph

both equations and proportions are better.
