Direct Inverse Variations

State what type of variation the equation represents. (a)  

• Direct

• Inverse

• Joint

• None

Given that y varies inversely with x, if x =7 and y = 4, what is y when x = 2?

• 14

• 10

• 2

• -14

Does the equation show an inverse variation? 
y=10/x

• yes

• no

If the both quantities are increasing or decreasing then its called as

• Direct Variation

• Inverse Variation

The image is an example of the graph of a(n)

• direct variation

• inverse variation

• neither

• both

If y varies inversely as x, and y = 32 when x = 3, find x when y = 15.

• 3/5

• 8/5

• 16/5

• 32/5

In this type of variation, both x and y are either increasing or both are decreasing (a)  

• indirect

• direct

• neither

In this type of variation, x and y are doing the opposite- when one is increasing, the other is decreasing (a)  

• inverse
