What is the slope of the line through (-7,-2) and (-6,7)

m = 9

Step-by-step explanation:

The slope of a line can be found through rise-over-run: dividing the change in y-coordinate over the change in x-coordinate -- (y₁ - y₂) ÷ (x₁ - x₂)

That looks like this: (-2 - 7) ÷ (-7 + 6) --> subtracting negative = adding positive

Add: -9 ÷ -1

Divide: 9

4 + 5 7/9= 9 7/9

step-by-step explanation:

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.
