Algebra (Class 61)
Overview
Today we work towards developing a process for finding the y-intercept of a line when we know the coordinates of two points on the line.
Textbook Sections
§8-3(Txt. p.360) Slope of a Line
§8-4 (Txt. p.366) The Slope-Intercept Form of a line.
Key Attitudes
Mathematics is about generalizing and applying patterns.
Key Ideas
The slope of a line can be found by finding the ratio of the change in y to the change in x.
The change in y and change in x can be found by subtracting the corresponding y-values or corresponding x-values.
The y-intercept can be found by using the slope to “move to” the y-axis.
Key Skills
Polynomial division
