Algebra II Honors—Day 3

2
Goals for Today Check Homework – Turn in Parent Contact Info with signatures (if not done already) – In-class warmup (pick up at front of room) – Show me your homework and get a homework stamp – Go over questions Essential Questions – New material and continue review of properties Homework Assignment—Handout

3
Essential Questions How do I determine the accuracy of my answers? How do I calibrate my axes on a coordinate plane within the context of the data? How do I graph a linear equation?

4
Properties of Equality Reflexive Symmetric Transitive Substitution

5
Accuracy of Answers Units of measurement – A geometric example Rounding off – A banking example Exact answers vs. approximations – Irrational or decimal approximations?

6
Coordinate Plane Axes Origin Quadrants Domain Range

7
Graphing Linear Equations Decide on the appropriate labels for your axes and an appropriate scale. What two things are being compared? Use a table or a formula to draw your graph. Determine the formula from the graph.

8
Homework Handout—Unit 1 Lessons 1 and 2 – Problems 1 and 2 deal with units of measurement and determining which are most accurate. – Problem 3 is about rounding off to estimate answers. – Problem 4 is a long two-part problem asking you to determine two linear equations and analyze each of them.
