State whether the relationship between the variables in the table is a direct variation, an inverse variation, or neither. If it is a direct or inver...
The constant of variation in a direct variation is the constant (unchanged) ratio of two variable quantities. The formula for direct variation is. where k is the constant of variation. Example 1: If y varies directly as x and y = 15 when x = 24, find x when y = 25. Find the constant of variation.
