Answer:

   18 kilometers per hour

Step-by-step explanation:

speed = distance /time

     distance given is 3 kilometers  

      time given is 10 minutes  

the answer is supposed to be given in hours so you convert the 10 minutes to hours .hence ;  

                       if 60 minutes = 1 hour  

                  what about 10 minutes= ??

                     10 minutes  *  1 hour /60 minutes  

                  answer is 1/6 hours

so speed = 3 kilometers/1/6 hours  

               =18 kilometers per hour

Determine which line the point (2, -1) lies on. y = 2x + 1 y = x + 5 y = 2x - 5 y = x - 2
inna [77]

To determine which line the point lies on, you can just plug in one of the numbers into the equations to see if it equals out.

(2, -1)  I will use the 2 and plug it in for x in the equation.

y = 2x + 1

y = 2(2) + 1

y = 5            The point does not lie on this line because when x = 2, y = 5  (2, 5)

y = x + 5

y = 2 + 5

y = 7          The point does not lie on this line because when x = 2, y = 7  (2, 7)

y = 2x - 5

y = 2(2) - 5

y = 4 - 5

y = -1           The point does lie on this line because when x = 2, y = -1  (2, -1)

y = x - 2

y = 2 - 2

y = 0      The point does not lie on this line because when x = 2, y = 0  (2, 0)
