For each graph, calculate the slope of the line.
Whew is the slope between 2,6 and 8,4

-1/3

Step-by-step explanation:

First, slope is change in y over change in x, or rise over run. Plugging these points in, (y2-y1)/(x2-x1)=(6-4)/(2-8), or 2/-6, simplifying, the slope= -1/3.

good job you smart son of a gun you are smarter that einstein. 7

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
