Graphing Linear Equations in Slope-Intercept Form

Mrs. Yaod introduces graphing linear equations using the slope-intercept form. She explains the concept of slope as the rate of change and demonstrates how to calculate it using two points. The lesson covers different types of slopes: positive, negative, zero, and undefined. Students practice finding slopes through exercises and learn to determine slope and intercept from linear equations. The video concludes with graphing linear functions and identifying x and y intercepts.

What does the 'm' in the slope-intercept form of a line represent?

• The y-intercept of the line

• The slope of the line

• The x-intercept of the line

• The constant term

In the slope formula, what does 'rise over run' represent?

• Change in y over change in x

• Change in x over change in y

• None of the above

• Total distance traveled on the graph

How do you calculate the slope if given two points (2,3) and (5,11)?

• (5-2) / (11-3)

• (11-3) / (2-5)
