Understanding Slopes and Their Types

The video tutorial explains the concept of slope, defined as rise over run or change in y over change in x. It covers the four main types of slopes: positive, negative, zero, and undefined, using examples to illustrate each. Positive slopes rise to the right, negative slopes fall to the left, zero slopes are horizontal, and undefined slopes are vertical. The tutorial also provides a visual guide to understanding slopes and encourages viewers to explore further resources for a deeper understanding.

What is the slope of a line defined as?

• The distance between two points

• The midpoint of a line

• Rise over run or change in y over change in x

• The angle of a line

If a line moves up 2 units and right 2 units, what is the slope?

• 0

• -1

• 2

• 1

What does a positive slope indicate about the direction of a line?

• The line is horizontal

• The line is vertical

• The line tilts to the right

• The line tilts to the left

If a line moves up 3 units and left 1 unit, what is the slope?

• -1

• 1

• -3

• 3

What does a negative slope indicate about the direction of a line?

• The line is horizontal

• The line is vertical

• The line tilts to the right

• The line tilts to the left

What is the slope of a horizontal line?

If a line does not rise but moves right 2 units, what is the slope?

• Undefined

• 2

• 1

• 0

What is the slope of a vertical line?

• -1
