The slope of a graph line is determined by calculating the:

• change in the horizontal values divided by the change in the vertical values.

• change in the horizontal values multiplied by the change in the vertical values.

• change in the vertical values divided by the change in the horizontal values.

• change in the vertical values multiplied by the change in the horizontal values.

Steven threw 4 balls into the air and recorded their heights.
Ball M had a max height of 2.0 m
Ball N had a max height of 1.5 m
Ball O had a max height of 4.2 m
Ball P has a max height of 3.0 m

• Ball P went twice as high as Ball N
• Ball M went twice as high as Ball N.
• Ball P went two meters higher than Ball O
• Ball N went two meters higher than Ball 0

On a distance-time graph, what does a horizontal line indicate?

• Object increased  in speed
• Object decreased in speed
• Object stopped moving.
• Object changed direction.
