Using the image, find the distance between the points given on the graph.

========================================================

Explanation:

The two endpoints of the segment are (0,-2) and (4,-1)

So this means

(x1,y1) = (0,-2)

(x2,y2) = (4,-1)

Use the distance formula

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
