Graphing Linear Equations

The slope of a horizontal line is:

• 0
• undefined
• -1
• 1

The slope of a vertical line is:

• 0

• undefined

• 1

• -1

If a line has a slope of -2, what does this indicate about its direction?

• It is vertical

• It rises to the right

• It falls to the right

• It is horizontal

• It falls to the right

• It is horizontal

• It rises to the right

• It is vertical
