Nakida read that the number of times a cricket chirps depends on the temperature of the air. The scientists found that the number of chirps per minute is equal to 0.23 times the temperature of the air, in degrees Fahrenheit, plus forty. a. Write an equation that represents the number of times a cricket chirps given the temperature in degrees Fahrenheit.
b. Graph the equation.
c. Identify the slope and y-intercept of the graph. Explain what each means in terms of the situation.

0.6

39mph

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."
