Learn how to use the slope formula to determine the slope between two points

The video tutorial reviews a problem related to the slope formula, emphasizing its importance and consistency between any two points. It explains how to calculate the slope using the change in Y and X coordinates, highlighting the need for consistency in subtraction order. The tutorial also stresses the importance of using parentheses in calculations and discusses the placement of negative signs in fractions, clarifying that the position of the negative sign does not affect the result.

What does the slope of a line represent?

• The change in vertical and horizontal positions between two points

• The angle of a line with the x-axis

• The midpoint of a line segment

• The distance between two points

Why is it important to label points as X1Y1 and X2Y2 when using the slope formula?

• To ensure the points are on the same line

• To differentiate between the x and y coordinates

• To make the calculation easier

• To avoid using negative numbers

What is the slope of a line if the change in y is 3 and the change in x is 5?

• -5/3

• -3/5

• 5/3

• 3/5

How should negative signs be handled when calculating slope?

• Always place them in the denominator

• Always place them in the numerator

• Avoid using negative signs altogether

• It doesn't matter where they are placed as long as the calculation is consistent
