Finding Slope: From Ordered Pairs to Graphs

The video tutorial covers the concept of slope, also known as the rate of change, and explains how to find it using ordered pairs, tables, and graphs. It introduces the slope formula and demonstrates its application through examples. The tutorial also discusses special cases of slope, such as zero and undefined slopes, and illustrates how to determine slope graphically using the rise over run method.

What is the slope or rate of change defined as?

• The ratio of change in x to change in y

• The difference between changes in x and y

• The ratio of change in y to change in x

• The sum of changes in x and y

Which formula is used to find the slope between two points?

• x1 - x2 / y1 - y2

• y2 - y1 / x2 - x1

• x2 - x1 / y2 - y1

• y1 - y2 / x1 - x2

What is the slope if the y-values of two points are the same?

• Negative

• Zero

• Positive

• Undefined

What does it mean if the slope is undefined?

• The line is vertical

• The line has a positive slope

• The line is horizontal

• The line has a negative slope

How do you find the slope from a table of values?

• By adding the x and y values

• By using the slope formula with any two points

• By subtracting the x values from the y values

• By dividing the x values by the y values
