For each table, determine whether it shows a direct variation, an inverse variation, or neither.
Write the equation for the direct or inverse variation when it exists.
x y direct or inverse?
5 6
10 12
30 25
To determine if this table shows direct or inverse variation, we need to check if there is a constant ratio between x and y.
If we divide y by x for each pair of values, we get:
6/5 = 1.2
12/10 = 1.2
25/30 = 0.833
Since the ratios are not constant, this table does not show direct or inverse variation.
