(-1,4) and (3,16) in point slope form

The equation of the line is y - 16 = 3(x - 3)

Step-by-step explanation:

To find the equation of this line, we first need to find the slope. To do that, we use the slope equation.

m(slope) = (y2 - y1)/(x2 - x1)

m = (16 - 4)/(3 - -1)

m = (16 - 4)/(3 + 1)

m = 12/4

m = 3

Now that we have the slope, we can use it and either point in point-slope form.

y - y1 = m(x - x1)

y - 16 = 3(x - 3)

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
