Finding the Equation of a Line from a Graph

This video tutorial teaches how to write the equation of a line using information from a graph. It covers the concepts of ordered pairs, y-intercept, and slope, explaining how these elements form a linear equation. The tutorial demonstrates calculating the slope using two points and introduces the slope-intercept form. It also highlights common mistakes in selecting coordinate pairs and provides a step-by-step guide to writing the equation of a line, including verification with a point on the line.
