Finding Slope from a Table

The video tutorial explains how to find the slope of a line using a table of values. It introduces the concept of slope as the change in Y over the change in X, using the Greek letter delta to represent change. The tutorial provides multiple examples, demonstrating how to calculate slope from tables, simplify fractions, and ensure consistency across different points. It also covers how to handle tables presented in different orientations, emphasizing the importance of maintaining the correct order of changes in Y and X.

What is the formula for finding the slope of a line?

• Change in Y over Change in X

• Sum of X and Y

• Change in X over Change in Y

• Difference of X and Y

What does the Greek letter delta (Δ) represent in the context of slope?

• Sum

• Product

• Difference

• Change

In the first example, what is the change in Y from 12 to 9?

• -2

• 3

• 2

• -3

Why is it important to keep the order of changes in Y and X consistent?

• To simplify the fraction

• To avoid confusion

• To make the table look neat

• To ensure the slope is calculated correctly

In the second example, what is the change in X from 1 to 5?

• 3

• 2

• 1

• 4

What is the slope calculated in the second example?

• 2/1

• 4/1

• 1/4

• 1/2

In the third example, what is the change in Y each time?

• 1

• 2

• 3

• 4

How is the slope simplified in the third example?

• 1/2

• 2/1

• 2

• 1/1

In the final example, what is the change in Y from -4 to -9?

• 4

• -4

• 5

• -5

What is the final slope calculated in the last example?

• 1

• -1

• 5

• -5
