Calculating Slope from Changes

The video tutorial teaches how to find the slope from a table of x and y values. It explains the concept of slope as the change in y divided by the change in x. The tutorial provides examples with consistent and varying changes in values, demonstrating how to calculate the slope in each case. It concludes with practice problems for viewers to apply what they've learned.

What is the slope of a line if the change in Y is 2 and the change in X is 1?

• 1/2

• 2

• 3

• 1

How do you calculate slope from a table?

• Difference of X and Y

• Change in Y over change in X

• Change in X over change in Y

• Sum of X and Y

In the example with X values 2, 4, 6, 8 and Y values 0, 3, 6, 9, what is the slope?

• 3

• 1/2

• 2/3

• 3/2

What is the slope if the change in Y is 3 and the change in X is 2?

• 3/2

• 2/3

• 1/2

• 1

When changes in Y are 2, 6, and 4, and changes in X are 3, 9, and 6, what is the slope?

• 2/3

• 1

• 3/4

• 1/2

In a table with inconsistent changes, how should you calculate the slope?

• Use only the first change

• Ignore the changes

• Use the average change

• Calculate piecewise

What is the simplified form of the slope if the change in Y is 6 and the change in X is 9?

• 1

• 1/2

• 3/4

• 2/3

If Y values change from -3 to 0 and X values change from 1 to 7, what is the slope?

• 2

• 1/3

• 1/2

• 1

In the practice example, what is the slope when Y changes by 1 and X changes by 2?

• 1

• 3/2

• 1/2

• 2

In the final example, what is the slope when Y changes by 6 and X changes by 8?

• 1/2

• 2/3

• 3/4

• 1
