What to know for the TEST
There are three concepts you need to know:
1) Create an equation from a context, table, or graph
2) Identify Key Features of Graphs
3) Solve Inverse Variation Equations (by hand, with graphs, and tables)
3
Create from Context
Reading a story can get stressful, so here are tips on how to write an equation to help you solve problems
First, find your variables. There will be one complete pair of x & y.
Then, multiply them for your Constant of Prop. K
Substitute that into y=K/x
4
Create from Table
This is similar, but no story!
Just remember y=k/x means k=x*y
you can multiply ALL x&y pairs to find k and substitute it into the equation!
5
Create from Graph
Find several points on the graph (look for whole number pretty points!)
Multiply their x&y values to find K
Sub into the equation!
6
Lastly: Situations with 2 variables
Remember, you're just using that if y=k/x, then k=x*y. Multiply that set of variables to find K!
