Choose the point-slope form of the equation below that represents the line that passes through the point (-1,6) and has a slope of -3 a) y-6=-3x-3 b) y-6=-3 (x+1) c)y=-3x+3 d)3x+y=3

B)

Step-by-step explanation:

The equation  ( in point slope form) of a line passing from (a,b) and has slope (m) is given by :-

Now, the equation ( in point slope form) of the line that passes through the point (-1,6) and has a slope of -3 will be:-

if x = 1, then the answer is 3.5

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
