The point (12,9) is included in a direct varation. What is the constant of variation
In a direct variation, the relationship between two variables can be expressed as y = kx, where k is the constant of variation. To find the constant of variation, we can use the given point (12, 9).
Substituting the given values into the equation, we have 9 = k(12).
Dividing both sides by 12, we get k = 9/12 = 3/4.
Therefore, the constant of variation is 3/4.
