Finding Missing Coordinates with the Slope Formula

What is the first step in finding a missing value using the slope formula?

• Substitute values into the slope formula

• Simplify the equation

• Label the given information

• Cross multiply to solve the equation

What happens if you incorrectly label your given information?

• You can still find the correct answer

• It has no effect on the solution

• You will likely get the wrong answer

• You will solve for the wrong variable

What is the slope formula used in the video?

• m = (y2 - y1) / (x2 - x1)

• m = x2 - x1

• m = y2 - y1

• m = (y2 + y1) / (x2 + x1)

How do you solve for x when given the slope and one missing x value?

• By adding the y values

• By subtracting the slope from y values

• Using cross multiplication

• Through division only

What is the result of cross multiplying when solving for a missing value?

• A proportion

• An undefined equation

• A complex number

• A simplified equation

How can you check if your solution for a missing value is correct?

• Substituting back into the original equation

• By graphing the equation

• Asking a friend

• Guessing and checking

Where should the negative sign be placed when dealing with a negative slope?

• In both the numerator and denominator

• In the denominator only

• In the numerator or the denominator, but not both

• Outside the fraction

What does it mean if the slope is negative?

• The line is horizontal

• The line is vertical

• The line slopes downwards from left to right

• The line slopes upwards from left to right

What does an undefined slope indicate about the x values?

• The x values are zero

• The x values are equal

• The x values can be any number

• The x values are different

How do you handle the slope when it is undefined?

• By ignoring the slope

• By assuming the slope is zero

• By setting the denominator to zero

• By setting the numerator to zero
