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)

What letters are used to label the first point in the slope formula?

• A and B

• M and N

• X1 and Y1

• X2 and Y2

What is the first step in solving for R in the equation -3 = (9 - R) / 3?

• Divide both sides by 3

• Multiply both sides by 3

• Subtract 9 from both sides

• Add 3 to both sides

After multiplying both sides by 3 in the equation -3 = (9 - R) / 3, what is the next step?

• Multiply both sides by -1

• Subtract 9 from both sides

• Divide both sides by -1

• Add 9 to both sides

What is the value of R in the equation -3 = (9 - R) / 3 after solving?

• R = 9

• R = -18

• R = -9

• R = 18

What should you do first when solving a slope problem with a fraction?

• Cross-multiply

• Label all points

• Divide the numerator by the denominator

• Add the numerator and denominator

In the equation -2 = (6 - 7) / (8 - x), what is the first step to solve for x?

• Add 7 to both sides

• Subtract 6 from both sides

• Divide both sides by 2

• Cross-multiply

What is the result of cross-multiplying in the equation -2 = (6 - 7) / (8 - x)?

• 2 * (8 - x) = 1

• -2 * (8 - x) = -1

• -2 * (8 - x) = 1

• 2 * (8 - x) = -1

What is the final value of x in the equation -2 = (6 - 7) / (8 - x) after solving?

• x = 8

• x = 6

• x = -6

• x = -8

What is the key tip mentioned for solving slope problems?

• Check your work twice

• Always use a calculator

• Label everything

• Memorize all formulas
