Linear Function and SOE review guide

This will be your most challenging test to date so I suggest you work hard in class and ask questions when you have them.

Here is what you are expected to know:

how to write the equation for a linear function
how to solve a system of equations
how to set up a system from a word problem
how to create a graph that shows two people of different speeds racing

Here is a video on how to solve systems

here is a video on how to solve the word problems

Don't forget to plug in the first variable to solve for the second when solving systems!

Knowing the slope formula helps but you can still find slope by plotting the points on a coordinate plane and then counting rise and run.

I saw on your projects that many of you were not sure how to write the equation for a vertical or horizontal line.  Check out the projects on the wall to see how that is done, ask us or google how to do so.
