What is the slope of the line that passes through (8,4) and (6,7)?

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

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct

if you're trying to figure out how much each ounce cost it would be 0.20

cents each ounce
