Solving for Missing Coordinates with the Slope Formula

This video tutorial by Method Man covers solving slope problems using the slope formula. It begins with an introduction to the slope formula and the importance of labeling points. The tutorial then demonstrates solving for R in a slope equation, followed by a more complex problem involving a fractional slope. The video emphasizes the importance of labeling and provides step-by-step solutions, encouraging viewers to practice and subscribe for more lessons.

What is the formula for slope?

• m = (X1 - X2) / (Y1 - Y2)

• m = (Y1 - Y2) / (X1 - X2)

• m = (X2 - X1) / (Y2 - Y1)

• m = (Y2 - Y1) / (X2 - X1)
