Finding Slope from the Slope-Intercept Form

Mr. Buffington introduces the slope-intercept form of a line, explaining how to identify the slope and Y-intercept from an equation. He provides practical examples and interactive practice questions to reinforce understanding. The video emphasizes the importance of recognizing the number in front of X as the slope and the constant term as the Y-intercept, making it easier to interpret line equations without graphing.

What is the slope intercept form of a line primarily used for?

• Finding the radius of a circle

• Solving quadratic equations

• Calculating the area under a curve

• Identifying the slope and Y-intercept of a line

What does the Y-intercept indicate in a line's equation?

• The point where the line crosses the X-axis
