Carina records the height of a candle after x hours burning. Her data are shown in the graph below. Burning Candle
A graph has time burned (hours) on the x-axis and candle height (centimeters) on the y-axis. A line goes through points (2, 6), and (1, 8).

Which is the best estimate for the height of the candle after 1 hour?
4 cm
5 cm
8 cm
9 cm

- "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."
