What is the slope of a line that passes through the points (1, -2) and (-3, -6)?

A) -2
B) -1
C) 1
D) 2

C) 1.

Step-by-step explanation:

The slope = difference in y values / corresponding difference in  x values

= (-6 - (-2)) / (-3 - 1)

= -4 / -4

= 1.

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.
