Which graph represents a proportional relationship?

Graph represented by option A.

Step-by-step explanation:

We are asked to choose the graph that represents a proportional relationship.

We know that a proportional relationship is in form , where k represents constant of proportionality.

We can see that graph represented by option A is the correct choice as the y-intercept is 0.

The equation of the graph represented by option A would be , where m represents slope of line.

Therefore, option A is the correct choice.

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.

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.
