The constant of proportionality is 25 and the distance at 10 seconds is 250 m.
To find the constant of proportionality, find the slope of the graph.
- m = Δy/Δx
- m = 50 - 25 / 2 - 1
- m = 25
Now, input in slope intercept form of equation to find distance at 10 seconds.
- y = mx
- y = 25(10)
- y = 250 m
