Finding Slope and Graphing Slope-Intercept Form

What does the slope represent in a linear function?

• The distance between two points

• The vertical change between two points

• The horizontal change between two points

• The rate of change between two points

How is the slope described in terms of rise and run?

• Run over rise

• Sum of rise and run

• Rise over run

• Difference of rise and run

Which of the following is a correct formula for finding the slope between two points?

• (x2 - x1) / (y2 - y1)

• (y2 - y1) / (x2 - x1)

• (x1 - x2) / (y1 - y2)

• (y1 - y2) / (x1 - x2)

What must be true about the order of terms when using the slope formula?

• The y terms must come first

• The order of terms does not matter

• The order of terms must correspond

• The x terms must come first

If the slope between two points is calculated as 32/15, what does this represent?

• The line is vertical

• The line rises 32 units for every 15 units it runs

• The line is horizontal

• The line runs 32 units for every 15 units it rises
