Finding Slope from Equations, Tables, and Points

This video tutorial explains how to find the slope of a line from equations, tables, and two points. It begins with an introduction to the concept of slope, represented by the letter 'm', and how it describes the steepness of a line. The tutorial then covers finding slope from equations in the form y=mx+b, where the slope is the coefficient of x. It proceeds to explain how to determine slope from tables by calculating the change in y over the change in x. Finally, it demonstrates two methods for finding slope from two points: converting the points into a table or using the slope formula.

What does the letter 'm' represent in the equation y = mx + b?

• The x-intercept

• The slope

• The constant term

• The y-intercept

What is the slope formula for finding the slope between two points?

• (x2 - x1) / (y2 - y1)
