**Lesson 12.1 Inverse Variation pg. 642**

Objectives: To graph inverse variation. To solve problems involving inverse variation.

2
Inverse Variation y varies inversely as x if there is some nonzero constant k such that xy = k

3
**Inverse Variation Problems**

To solve some inverse variation problems, there are two steps: (1) First find the value of k (2) Use the value of k to find a specific value of x or y

4
**Graphing Inverse Variation**

To graph inverse variation choose values for x and y whose product is k

5
**Ex. 1: Graphing inverse variation**

Graph an inverse variation in which y varies inversely as x, and y=1 when x=4

6
**Graph an inverse variation in which y varies inversely as x, and y=-6 when x=-2**

10 -10

7
**Product Rule for inverse variation**

The product rule x1 y1 = x2y2 can be used to solve inverse variation problems.

8
**1. If y varies inversely as x and y = 5 when x =12, find x when y = 15**

Ex. 2: Write and inverse variation equation that relates x and y. Assume that y varies inversely as x. Then solve. 1. If y varies inversely as x and y = 5 when x =12, find x when y = 15

9
**2. If y varies inversely as x and y = 8 when x =6, find y when x = 4**
