The points (0, 18) and (–8, 10) fall on a particular line. What is its equation in slope-intercept form?

y = x + 18

Step-by-step explanation:

slope:

  m = (y₂ - y₁) / (x₂ - x₁)

      = (10 - 18) / (-8 - 0)

      = -8 / -8

      = 1

y-intercept using m from above and anyone of given points, let's use (0, 18):

  y = mx + b

  (18) = 1(0) + b

  b = 18

Using m and b from above form equation of line:

  y = mx + b

  y = 1x + 18 or y = x + 18

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

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
