Finding Slopes from Two Points in Slope-Intercept Form

This video tutorial explains how to find the slope of a line given two points. It introduces the slope formula, m = (y2 - y1) / (x2 - x1), and breaks down its components. The tutorial provides multiple examples, including cases with negative coordinates, zero slope, and undefined slope, to illustrate the application of the formula. The video emphasizes the importance of labeling coordinates and simplifying fractions, and it concludes with a review of the key concepts.

What is the formula for finding the slope of a line given two points?

• m = (y1 - y2) / (x1 - x2)

• m = (x1 - x2) / (y1 - y2)

• m = (x2 - x1) / (y2 - y1)

• m = (y2 - y1) / (x2 - x1)

In the formula m = (y2 - y1) / (x2 - x1), what does y2 represent?

• The x-value of the first point

• The y-value of the second point

• The x-value of the second point

• The y-value of the first point

Given the points (2, 1) and (3, 4), what is the slope of the line passing through these points?

• 1

• 3

• 2
