Unit 6

Introduction to Unit 6:  Linear Models and Tables      Key Terms




In this unit, we will continue to look at functions, particularly linear functions. We will revisit finding rate of change of various applications, or real-world, problems. 

 Describing what we see in graphs is an important skill.   

 We will analyze graphs that represent relationships among two variables. This means we are determining if the graph is linear or non-linear, where is the graph increasing, or where is the graph decreasing.  This information will help us make determinations regarding the original data we were given. 

 Sometimes data doesn't fall in a nice straight line, but we can still use linear functions to help us find the line of best fit. This is called linear regression. 

 Finally, we'll wrap this unit up by constructing and interpreting two-way tables.  Two-way tables help us understand data from 2 variables to see if there is any connection or relationship between the 2 variables.

Essential Questions:

  • How do we construct a function to model linear relationships?
  • How do we determine rate of change from a graph or from a table of values?
  • How do we analyze a graph qualitatively?
  • How do we plot and interpret bivariate data?
  • How can we use straight lines to model relationships between two quantitative variables?
  • How can we solve problems using linear equations with the bivariate data?
  • How do we construct and interpret two-way tables?
