Slope and y-intercept

-2/3

Step-by-step explanation:

(9, 2)

(3, -2)

Slope form: y/x

Let's solve for x first: 9-3= 6

Now, insert x into the equation: y/6

Now for y: 2⇒-2= -4

Therefore -4/6, aka -2/3, is your answer.

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.
