Exploring X- and Y-Intercepts in Algebra

The video tutorial explains how to graph linear equations by plotting points and drawing lines. It covers the concept of x and y-intercepts, demonstrating how to find these intercepts for different linear equations. The tutorial uses examples to illustrate the process of plotting points and drawing lines, and it explains the significance of intercepts in understanding the graph of an equation.

What is the linear equation introduced at the beginning of the video?

• y = -1/2x + 3

• y = 1/2x - 3

• y = x - 3

• y = 2x + 3
