Explanation Given Information: The provided relationship y varies directly as x and when y = 18 , x = 4 . Formula used: To finding a variation constant k the following steps are written below, Step 1. Write a general variation model that relates the variables given in the problem. Let k represent the constant of variation. Step 2. Solve for k by substituting known values of the variables into the model from step 1. And, Definition of direct variation is, For a non-zero real constant number k . Then, The y varies directly as x , y ∝ x Then, the y directly proportional to x , y = k x Calculation: Definition of direct variation is, For a non-zero real constant number k

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
