The students solved the problems and then put them into groups.
First, they needed to sort out all of the linear problems.
Class put their Linears into categories...
Definitely Linear, Definitely not, still unsure
Class discovered that this (below) was linear instead of line of best fit.
-Look for slope
-Put points on graph and see if they are missing
-expand table
General Statements that cannot be linear
-exponent=not linear
Which ones are line of best fit?
Inverse? Which problems were inverse?
R-51
If something is line of best fit, linear, or inverse what are some things to keep in mind?
What kind of clues tell me it is Linear?
-something goes up or down at a constant rate
What kind of clues tell me Line of Best fit?
-Somewhat scattered, but not random
-It has a linear trend
What kind of clues tell me Inverse?
- Constant w/ 2 variables
What are some things that will be on tomorrow's test?
-Put an equation in y=mx+b form
-Give an equation, graph, or a table and ask for the others (Including a word problem)
-Slope, x and y intercept
-parallel lines and/or perpendicular lines
-Given Line of Best fit data,will need to do general line, equation, and graph.
-Inverse: Ask for an equation
-Write equation when given:
*graph
*couple of points
*table
*Word Problem
*Constant and 2 other variables (If there is a constant, it is inverse)
-Solve for x!!!!!!
-Great mathematical observations!
-Word Problems: Graphs, tables, equations
*Linear, Line of Best Fit, Inverse
