Finding X and Y Intercepts in Algebra

This video tutorial covers the concepts of X and Y intercepts, explaining their definitions and how to find them on a graph. It provides step-by-step instructions for solving equations to determine these intercepts, using examples to illustrate the process. The video also emphasizes the importance of expressing intercepts as coordinate points.

What is the x-intercept of a graph?

• The y-coordinate of the line

• The slope of the line

• The point where the line crosses the x-axis

• The point where the line crosses the y-axis

What is the y-intercept of a graph?

• The slope of the line

• The point where the line crosses the x-axis

• The point where the line crosses the y-axis
