Graphing Using Slope-Intercept Form

Question:
Graph the equation y equals two-fifths x minus 4 by first plotting the y-intercept, then using the slope to find at least two more points. Verify that all points satisfy the equation.

Graphing Using Slope-Intercept Form

This lesson covers how to graph a linear equation written in slope-intercept form by identifying the slope and y-intercept, plotting key points using rise-over-run, and verifying that each point satisfies the original equation. Students practice the complete graphing process from equation to plotted line.

In this lesson, you will learn to:
• Identify the slope and y-intercept from an equation written in slope-intercept form.
• Plot the y-intercept and use the slope to locate additional points on the line.
• Verify that plotted points satisfy the original linear equation by substitution.
• Draw and interpret the graph of a linear equation, including identifyin
