Understanding Slope from a Table

What is the formula for calculating the slope of a table?

• Product of X and Y values

• Difference in X values divided by difference in Y values

• Sum of X values divided by sum of Y values

• Difference in Y values divided by difference in X values

In the first example, what is the change in the Y values?

• Adding 2

• Subtracting 3

• Adding 3

• Subtracting 2

In the second example, what is the slope of the table?

• 3

• 5

• 1

• 0

In the final example, what is the result of dividing the rise by the run?

• Negative 2

• Positive 2

• Zero

• Negative 4

What happens to the slope when both the rise and run are negative?

• The slope becomes zero

• The slope becomes negative

• The slope remains unchanged

• The slope becomes positive
