2.  Direct variation

3.   If Y divided by X always gives you the same number then it is direct variation.  I remember this because direct and divide by start with “D” Another short cut

4.   Each X is multiplied by 3 to get the Y value Example as table X123 Y369

5.  Example as graph

6.   Y=3x  Y=1/2X  2y=X because divide both sides by 2 resulting Y=1/2X Example as equation

7.  1.Y=X+3 2.(0,0)(1,6)(2,12) 3. You try which examples are direct variation X123 Y456

8.   Relationship between two variable written Y= K/x Huh, again? If Y equals a constant divided by a given X, then it is an inverse variation. Inverse variation

9.   If you multiple X and Y and they always equal the same constant  then it is an inverse variation Another short cut

10.  Example as graph

11.  x6212 y6183 Example as chart

12.   This time you create a chart containing an inverse variation. You try

13.  summary
