Algebra (Class 39)
Overview
A Visual Approach to Functions
We continue our work with linear relationships and with our work on improving our ability to solve second degree trinomial equations using ZPP.
Key Attitudes
Mathematics is about reasoning.
Key Ideas
A person’s walking speed (rate) is represented by the slope of the line on a graph of distance compared to time.
A person’s walking rate can be calculated from data in a table of distance versus time.
A linear equation relating distance and time can be written once the persons rate and his starting distance (y-intercept) are known.
Key Skills
Plotting points on a graph.
Filling in a table of values using the rate.
Handouts
