Finding Slope from a Table: Key Concepts and Applications

This video tutorial explains how to find the slope from points given in a table. It covers different methods to calculate slope, including using the rise over run concept and the slope formula. The video also discusses special cases of slope, such as horizontal and vertical lines, and how these affect the slope value.

What does 'delta' signify in the context of calculating slope?

• The symbol for division

• A specific point on the graph

• The difference between two values

• A type of mathematical operation

Which formula represents the slope calculation?

• Y2 + Y1 / X2 + X1

• Y2 - Y1 * X2 - X1

• Y2 - Y1 / X2 - X1

• Y2 / Y1 - X2 / X1

In the context of slope, what does 'rise' refer to?

• The formula used

• The graph plotted

• Change in y values

• Change in x values

What is the slope if the rise is -4 and the run is 2?

• 1

• -2

• 2

• -1

How do the delta y over delta x method and the slope formula compare in their results?

• They yield different results

• They yield the same results

• Only the formula method is correct

• Only the delta method is correct

What does a consistent slope across different points suggest about the line?

• The line is vertical

• The line is horizontal

• The line is curved

• The line is straight

If the rise changes but the run remains consistent, what can be inferred about the slope?

• It remains the same

• It becomes zero

• It changes

• It becomes undefined

What is the slope of a horizontal line?

• Undefined

• 0

• 1

• -1

What is the slope of a vertical line?

• 0

• Undefined

• -1

• 1

What happens to the slope calculation when the run is zero?

• It is undefined

• It is one

• It cannot be calculated

• It is zero
