What is the slope of the line in the graph?

Using the graph and the information given, he slope of the graph is

Step-by-step explanation:

1. First, we need to find two points on the graph in order to find the slope.

Let's use the points (0, 1) and (4, -2)

2. Next, we need to know the slope formula.

3. Now, we plug in the coordinate points.

4. Finally, we simplify this fraction and then you will have your slope of the graph.

So, the slope of the graph is

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
