Choose the equation that represents the graph below:

y = -2x/3 + 6

Step-by-step explanation:

y = mx+b

m = y2-y1/x2-x1

m = 2 - 6/6 - 0

m= -4/6 = -2/3

b = y-intercept = 6

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.

good luck on ur quiz test or homework. have a good day : )
