This means that for that line the value of y will increase or decrease i.e value of y will vary but the value of x will be the same. Suppose a vertical line passes through x =4 then for all the points on that line, x coordinate will always be 4 and y coordinate will change......\r<BR>\n" );

document.write( "Now in our case the line is paralled to vertical line x =5. This means line is parallel to a line for which the value of x is fixed that is 5. This means the all the points that lie on that line will have x coordinate as 5 and the y will be varying.....<BR>\n" );
document.write( "Now parallel lines means that the distance between the two lines is always same and they dont meet....so a line parallel to a vertical line will also be vertical.......since this line passes through (-4,2)...and is vertical...this means that x coordinate for all the points on this line will be same that is -4.....<BR>\n" );
