Calculating Slope and Ordered Pairs

The video tutorial explains how to find the slope given two ordered pairs. It begins by introducing the slope formula, which is the change in y over the change in x. The tutorial then guides viewers through labeling the ordered pairs as X1, Y1, X2, and Y2, and substituting these values into the formula. Finally, it demonstrates the calculation process to find the slope, resulting in a slope of 2/3.

What is the first step in finding the slope given two ordered pairs?

• Calculate the average of the pairs

• Divide the pairs by each other

• Multiply the pairs together

• Substitute the values into the slope formula

What does the slope formula represent?

• The sum of x and y values

• The change in y over the change in x

• The difference between x and y values

• The product of x and y values

In the slope formula, what is the change in y?

• The difference between the y values

• The sum of y values

• The average of y values

• The product of y values

How are the ordered pairs labeled for substitution?

• X1, X2, Y1, Y2

• A1, A2, B1, B2

• X1, Y1, X2, Y2

• M1, M2, N1, N2

What is the purpose of labeling the ordered pairs?

• To compare them

• To substitute them into the formula

• To make calculations easier

• To identify the pairs
