AOPS Algebra 1 Course, Lesson 12, 11/24/2019

Today, students continued to study the word problems associated with “rate”, driving from one place to another, average speed, working rate, rowing boat in downstream and upstream. The most challenging part is in the working rate, and people are involved in the work. In the practice class, students finished a few of rate questions and they should understand more about solving the questions by creating equations. In the new chapter, graphing lines, number line and Cartesian plane (coordinate plane) were introduced. ordered pairs are defined to represent the points in the coordinate plane.
