(b) At what temperature is the tire pressure 36 lbs. per square inch? 

(c) The slope of the line in the figure is $\displaystyle {m}=$       (Enter your answer as a fraction.)

(d) The slope means that there is a one lb. per square inch increase in tire pressure for each degree Select an answer increase decrease in temperature.

(e) The equation of the line in the figure is $\displaystyle {y}=$ Preview Question 6 Part 6 of 7
