Directly Proportional Graph Example. Therefore A is directly proportional to B. Example 1 A babysitters earnings are.
Example 1 A babysitters earnings are. If the constant is negative the graph will have a negative gradient. Y is directly proportional to x when x 15 y 30.
Likewise B1 times a factor of 3 equals B2.
If this produces closely similar results you can be certain your variables are directly proportional to. When we put gas in our car there is a relationship between the number of gallons of fuel that we put in the tank and the amount of money we will have to pay. If x 1 y 1 is the initial values and x 2 y 2 are the final values of quantities existing in direct proportion. When we replace the proportionality sign with an equal sign the equation changes to.
