At 72°F, a certain insect chirps at a rate of 101 times per minute, and at 81°F, they chirp 128 times per minute. Write an equation in slope-intercept form that represents the situation.

center= (-2,0)

radius= sqrt2/2

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."

yes   because as the functions are graphed they eventually will intersect unless otherwise
