Calculate the Slope Position (meters) Time (seconds)

Calculate the Slope x (m) T (s) Point One Point Two

Calculate the Slope x (m) T (s) Point One Point Two 9 m 1 m 2 s6 s

Calculate the Slope x (m) T (s) Point One: 2s, 9m Point Two: 6s, 1m 9 m 1 m 2 s6 s

Slope = Rise / Run x (m) T (s) Point One: 2s, 9m Point Two: 6s, 1m 9 m 1 m 2 s6 s Slope =  x /  t

Slope = Rise / Run Slope =  x /  t Slope = (x 2 - x 1 ) / (t 2 - t 1 ) Slope = (1m - 9m) / (6s - 2s) Slope = -8m / 4s Slope = -2 m/s Why does the negative tell us?
