Beware of the negatives finding the slope

The video tutorial addresses common student mistakes when calculating slope, especially when dealing with negative coordinates. It emphasizes the importance of using parentheses to avoid errors and provides a step-by-step example of calculating slope with negative values. The instructor suggests labeling points consistently and using visual aids like colored pens to keep track of operations.

What is the basic formula for calculating the slope between two points?

• Change in X over change in Y

• Change in Y over change in X

• Sum of X and Y coordinates

• Product of X and Y coordinates

Why is subtraction in the slope formula challenging when dealing with negative numbers?

• It requires multiplication

• It involves division

• It adds more negatives to the problem

• It requires addition

What is the recommended method to avoid mistakes when dealing with multiple negatives in slope calculations?

• Use a graph

• Use a calculator

• Use parentheses

• Use a ruler

In the example calculation, what is the result of subtracting a negative number?

• It becomes a larger negative number

• It becomes zero

• It becomes a positive number

• It remains the same

What is the final slope calculated in the example provided?

• 4

• 2

• 1

• 3
