It explains the slope-intercept form y=mx+b, where m represents the slope and b the y-intercept, and demonstrates how to find and interpret these values. It also addresses real-world applications of linear functions, such as modeling and predicting trends. Examples and exercises help reinforce understanding of these key concepts.

It also explores angles in the Cartesian coordinate system, covering quadrants, angles in standard position, and coterminal angles. This foundation is critical for understanding Trigonometry's broader concepts, with practical examples and checkpoints to ensure comprehension.

The slope of a vertical line is undefined. The equation of a horizontal line is of the form y = k, where k is any real number. The horizontal line will always intersect the y−axis at the point (0,k). The slope of a horizontal line is zero.
