What is the slope formula and where does it come from

The video tutorial explains the concept of slope, focusing on the change in Y and X coordinates. It uses practical examples, such as changes in earnings over weeks, to illustrate how to calculate differences. The tutorial emphasizes the importance of using subscripts to differentiate coordinate points and maintaining consistency in subtraction when applying the slope formula.

What is the primary focus when discussing slope in this section?

• The change in Y coordinates over the change in X coordinates

• The average of X and Y coordinates

• The total distance between two points

• The change in X coordinates over time

How can you formally calculate the change in earnings from week one to week two?

• By dividing the earnings of week two by week one

• By subtracting the earnings of week one from week two

• By multiplying the earnings of both weeks

• By adding the earnings of both weeks

Why are subscripts used in coordinate points?

• To simplify the calculation of distance

• To avoid using numbers in coordinates

• To make the points look more complex

• To differentiate between different X and Y values

What is a common mistake students make when using the slope formula?

• Using addition instead of subtraction

• Not being consistent with the order of subtraction

• Using the wrong formula for slope

• Ignoring the Y coordinates

What is the key takeaway regarding the use of the slope formula?

• Consistency in subtraction order is crucial

• The formula should only be used for graphs

• It is only applicable to positive slopes

• It is important to memorize the formula
