Store A is selling a 4-pound bag potatoes for $2.40. Store B is selling a 7-pound bag of potatoes for $2.80. Grasph two lines, one to represent the cost per pound of potatoes at Store A and one for Store B

if you use photomath right away it will give you the answer not like this app that you have to wait for people.

step-by-step explanation:

- "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."
