Question 11 (03.06 LC)
Choose the equation below that represents the line that passes through the point (7,-2) and has a slope of -3. (5 points)
O Y-7 = -3(x + 2)
O y + 2 = -3(x - 7)
Oy-2 = -3(x + 7)
O y + 7 = -3(x - 2)
Question 12

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.
