Type an equation for the following pattern

y = - x + 6

Step-by-step explanation:

Note the difference in consecutive terms of y is constant.

- = - 4 = 4 - = - = -

This indicates the pattern is linear with equation

y = - x + b

To find b substitute any ordered pair from the table into the equation

Using (3, 4), then

4 = - 2 + b ⇒ b = 4 + 2 = 6

y = - x + 6 ← equation for pattern

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
