Question

The pair of points is on the graph of an inverse variation. Find the missing value. (1.6, 6) and (8, y)

Answer 1

1.2

Explanation:

The x-value increases by a factor of 5 from 1.6 to 8 between the two points. Because the variation is inverse, the y-value must decrease by a factor of 5 between the two points.

6/5 = 1.2

The second point is (8, 1.2), corresponding to the 4th selection.

Answer 2

the answer is 1.2
