However, for the lines to be parallel, the distance between the lines always stays the same. Perpendicular lines meet at a right angle. A right angle is a quarter turn, which is 90 degrees (90Ëš).
The graphs above, \(y = 2x + 1\) and \(y = 2x - 2\) have the same gradient of 2. The lines are parallel. State the equation of a line that is parallel to \(y = 3x + 7\). To be parallel, two lines ...
