Consider the plot created from the residuals of a line of best fit for a set of data.
does the residual plot show that the line of best fit is appropriate for the data?
yes, the points have no pattern.
no, the points are evenly distributed about the x-axis.
no, the points are in a linear pattern.
yes, the points are in a curved pattern.

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
