C

Step-by-step explanation:

y=mx+b is the equation for a line, where m is the slope.

For a line to be parallel to each other, they must share the same m value.

In your equation, y=6x+8, 6 is the slope

The only answer that shares that slope of 6 is C.

I hope this helps! :)

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.
