Intro to Finding Slope of a Line

What is the slope of line segment "S" ?

Which of the lines have a positive slope?

• A

• D

• E

• I

Which of the lines have a slope of ZERO?

• A

• D

• E

• I

When we used the triangles to find slope, we counted the heights and bases of the triangles and then divided (or simplified a fraction). Which of the following is NOT another way to count the same things to find slope?

What is the slope of the slide?

A triangle was drawn to find the slope of this line. Which is the "vertical distance" (height) of the slope triangle?

Which of the following is NOT a number that could describe the slope of the line shown?

• segment AC would be shorter than AB

• segment AC is steeper than AB and BC

Which of the lines has a negative slope?

• D

• F

• G

• H

Line AE has a negative slope. Why?

• If you read the line from left to right, it slants downward.

• It's actually a positive AND negative slope, because there are arrows going up and down.

• It's negative because some of the coordinates on the line are negative.

• It's negative because small triangles are drawn.
