Summary
Highlights
An overview of linear functions, defined as functions with a straight line graph and a constant rate of change. The section covers the slope (rise over run), intercepts, and the definitions of domain and range.
Method taught for graphing a linear equation in standard form by solving for the x-intercept (where y=0) and the y-intercept (where x=0), then connecting the points.
Step-by-step instructions on graphing a linear function structured as y=mx+b, where 'm' is the slope (rise/run) and 'b' is the y-intercept.
Explanation of how to choose convenient x-values to calculate corresponding y-values, creating a table that helps verify the line's precision with three or more points.
Demonstration of techniques to graph a linear function when provided with either two coordinate points or a slope combined with a single coordinate point.
