Determining Slope from a Table

The video tutorial covers the concept of slope in linear equations, explaining how to find slope using graphs, formulas, and tables. It provides examples of calculating slope with different methods and discusses special cases such as zero and undefined slope. The tutorial aims to help students understand the relationship between vertical and horizontal changes in a line and how to apply this knowledge to solve problems.

What is the formula for finding slope using two points on a graph?

• y2 + y1 over x2 + x1

• y2 - y1 over x2 - x1

• y2 - y1 over x2 + x1

• y2 + y1 over x2 - x1

When using a table to find slope, what do you need to examine?

• The ratio of x to y values

• The changes in y and x values

• The sum of x and y values

• The product of x and y values

If the y-values in a table decrease by 2 each time and the x-values increase by 6 each time, what is the slope?

• 1/3

• 2/3

• -1/3

• -2/3

In the example where y-values change by 1 and x-values change by 2, what is the slope?

• 3/1

• 1/3

• 2/1

• 1/2

How do you simplify the fraction -2/6?

• -1/2

• 2/3

• 1/3

• -1/3

What is the slope when there is no change in y-values but x-values increase?

• Undefined

• Zero

• Positive

• Negative

What is the slope when y-values increase but there is no change in x-values?

• Undefined

• Zero

• Positive

• Negative

What happens to the slope if the change in y is zero?

• The slope is undefined

• The slope is negative

• The slope is zero

• The slope is positive

What is the slope if the change in x is zero?

• The slope is positive

• The slope is negative

• The slope is zero

• The slope is undefined

Which method can be used to find the slope if you have a table of values?

• Using the ratio of x to y values

• Using the product of x and y values

• Using the sum of x and y values

• Using the changes in y and x values
