What is the equation in point slope form of the line that passes through the points (-1, 4) and (3,-4) ? a. y-3=-2(x+4) b. y-4=2(x+3) c. y+4=-2(x-3) d. y+4=2(x-3)

The point-slope form:

The formula of a slope:

We have the points (-1, 4) and (3, -4). Substitute:

it would be:

c.parallelogram.

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
