Understanding Slope Calculation

The video tutorial explains how to calculate the slope between two points, (5, 4) and (9, 2). It begins by introducing the slope formula, which is the difference in y-values divided by the difference in x-values, also known as 'rise over run'. The tutorial then labels the ordered pairs and demonstrates how to substitute these values into the formula. Finally, it performs the calculations to find the slope, which is -2/4, simplifying to -1/2.

What is the formula used to calculate the slope between two points?

• Y2 - Y1 over X2 - X1

• X2 - X1 over Y2 - Y1

• Y1 - Y2 over X1 - X2

• X1 - X2 over Y1 - Y2

In the slope formula, what do the terms 'rise' and 'run' refer to?

• Both rise and run refer to the difference in Y values.

• Both rise and run refer to the difference in X values.

• Rise refers to the difference in Y values, and run refers to the difference in X values.

• Rise refers to the difference in X values, and run refers to the difference in Y values.

When labeling ordered pairs, which pair is typically labeled as (X1, Y1)?

• The second ordered pair

• The pair with the smaller Y value

• The first ordered pair

• The pair with the larger X value

What is the result of subtracting Y1 from Y2 in the given example?

• -4

• 4

• 2

• -2

What is the final slope calculated between the points (5, 4) and (9, 2)?

• -1/2

• -2

• 1/2

• 2
