Write the slope-intercept form of the equation of the line that passes through the given pointa, then graph the equation. 1) through:(-2,-2) and (0,-4) 2) through:(2,6) and (-4, -3)

answer: 1 and 3

step-by-step explanation:

5

step-by-step explanation:

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

113.1

step-by-step explanation:

v=4

3πr3=4

3·π·33≈113.09734
