8. Louise is painting around a window frame on the outside of her house.
Her ladder is 3.5 m long, and she placed it 1.0 m from the house.
a. What is the slope of this ladder? Round to one decimal place.
b. If she wants to follow the 1 in 4 rule, is this ladder safe?

- "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."
