Question

In 1908 the winning Olympic discus throw was 134.2 feet.

In 1948, the winning throw was 173.2 feet.
What is the rate of change (SLOPE) for the distance of the
discuss throw from 1908 to 1948?

Answer 1

y = distance
x = time

(8 , 134.2)
(48, 173.2)

subtract y2-y1 and x2-x1 then divide y/x

173.2 - 134.2 = 39
48 - 8 = 40

39/40 is the rate of change or slope
