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...
Direct variation problems are solved using the equation y = kx. In this case, you should use p and q instead of x and y and notice how the word âsquareâ changes the equation. Step 2: Use the information given in the problem to find the value of k. In this case, you need to find k when p = 20 and q = 5.
