Calculating Intercepts of Linear Equations

This video tutorial explains how to calculate the x-intercept and y-intercept of linear equations in standard form. It provides step-by-step instructions and examples to find these intercepts by substituting zero for the other variable. The tutorial also demonstrates how to graph lines using these intercepts, emphasizing the simplicity and speed of the process. Several example problems are solved to reinforce the concepts, making it easy for learners to grasp and apply the techniques.
