The graph AB Shown in figure is a plot of a temperature of a body in degree Fahrenheit than slope of line AB is
(A) (5 / 9)
(B) (9 / 5)
(C) (1 / 9)
(D) (3 / 9)
Correct option: (A) (5 / 9)
Explanation:
Slope of BC = [(Y2 – Y1) / (X2 – X1)]
= [(100 – 0) / (212 – 32)]
= [(100) / (180)] = (5/9)
i.e slope of AB = slope of BC = (5/9)
