Understanding Slope and Desmos Functions

The video tutorial explains how to determine the slope of a line passing through two points. It covers two methods: using scratch paper to create a table and calculate the change in Y over the change in X, and using the Desmos calculator for a more efficient approach. The tutorial provides a step-by-step guide on inputting coordinates into Desmos, using the slope-intercept form, and converting decimal slopes to fractions. It emphasizes the importance of matching table entries and offers tips for accurate calculations.

What is the first step in determining the slope of a line through two points?

• Find the midpoint of the line

• Draw a perpendicular bisector

• Identify the coordinates of the points

• Calculate the distance between the points

What does 'm' represent in the equation y1 = mx1 + b?

• The midpoint

• The y-intercept

• The x-intercept

• The slope

What should you ensure when typing the slope-intercept form in Desmos?
