Linear Equations and Their Properties

This video tutorial explains how to draw straight line graphs using linear equations in the form y=mx+c. It covers filling out a table of values, substituting x values to find y values, and plotting coordinates to form a straight line. The tutorial includes examples and a practice problem to reinforce learning.
