Clayton read a digital thermometer of a substance as he runs an experiment. He records a low temperature of the substance as −18.42∘ F and a high temperature of the substance as 27.5°F.

He plots his data on a number line.

What is the distance between the coordinates on the number line?

the answer is b

step-by-step explanation:

answer-

a. the total cost of a taxi ride includes an initial charge of approximately $3.30

solution-

in the graph,

x axis represents the distance traveled and

y axis represents the total fare

the best fit line intersects the y axis approximately at 3.30 or y-intercept is 3.30. at x=0, i.e when the taxi is still, the value of y or the cost of the fare is 3.30. that means $3.30 is the fixed charge which will be levied along with the other fare.

the slope of the line represent the cost per mile. as the best fit line is straight line, so the price per mile is constant.
