LINR 1 | Lesson 3 | Making Connections (Increase or Decrease)

Making Connections
A line with a positive slope points up to the right.  

A line with a negative slope points down to the right.

A linear function is increasing when the \(x\)-values increase and the \(y\)-values increase.

This line is increasing.

An increasing line has a positive slope \((m>0)\).

A linear function is decreasing when the \(x\)-values increase and the \(y\)-values decrease.

This line is decreasing.

A decreasing line has a negative slope \((m<0)\).

A linear function is constant when the \(x\)-values increase and the \(y\)-values remain the same.

This line is a horizontal line.

horizontal line has zero slope \((m=0)\).

A linear function is undefined if the \(x\)-values are constant as the \(y\)-values vary.

This line is a vertical line.

vertical line has undefined slope.
