Summary of Slope Connections
| A line with a positive slope points up to the right.
The equation of a line with a positive slope can be written in the form \(y=mx+b\), where \(m>0\). |
A line with a negative slope points down to the right.
The equation of a line with a negative slope can be written in the form \(y=mx+b\), where \(m<0\). |
|
A line with a slope of zero is horizontal.
The equation of a horizontal line can be written in the form \(y=mx+b\), where \(m=0\). Example: \(y=0x+3\) or \(y=3\) |
A line with an undefined slope is vertical.
The equation of a vertical line can be written in the form \(x=c\), where \(c\) is a constant. Example: \(x=2\) |
