Write an equation of the line below.

y = 2/5 x - 4,

Step-by-step explanation:

The slope is negative as it rises to the right.

By counting the squares  we see that the slope is -2/5.

The y-intercept is -4  so the equation is y = 2/5 x - 4,

is this part of a question or something

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
