Vertical Lines
Special Example
The y axis is the vertical line that divides space in to three sets Set 1) the set of all points right of the y axis (+, y) Set 2) the set of all points left of the y axis (-,y) Set 3) the set of all points on the y axis (0,y) |
Horizontal Lines
Special Example
The x axis is the horizontal line that divides space in to three sets Set 1) the set of all points above the x axis (x, +) Set 2) the set of all points below the x axis (x,-) Set 3) the set of all points on the x axis (x,0) |
