(Coordinate Geometry) for a vertical line the slope is undefined. As you drag the points above, notice that the slope indicator goes away when the line is exactly vertical. The equation of a vertical line is x = a Where: x is the coordinate of any point on the line ais where the ... www.mathopenref.com/coordvertical.html Average Rating (0 votes) Horizontal line definition. (Coordinate Geometry) Horizontal line definition. (Coordinate Geometry) Examples Fig 1. Is the line horizontal? Determine if the line shown in Fig 1 is horizontal and write it's equation. The two points A,B on the line are at (7,7) and (39,7). The second coordinate in each pair is the y-coordinate which are 7, and 7. Since they are equal, the ... www.mathopenref.com/coordhorizontal.html Average Rating (0 votes) Parallel lines. (Coordinate Geometry) Parallel lines. (Coordinate Geometry) are equal. The slope can be found using any method that is convenient to you: From two given points on the line. (See Slope of a line).
