Easy -1.2 This is a straightforward coordinate geometry question requiring only two standard steps: finding the perpendicular gradient (-1/5) and using point-slope form to find the equation. It's routine bookwork with no problem-solving element, making it easier than average but not trivial since it requires correct manipulation to reach the specified form.
2 Find the equation of the line perpendicular to the line \(y = 5 x\) which passes through the point \(( 2,11 )\). Give your answer in the form \(a x + b y = c\) where \(a , b\) and \(c\) are integers to be found.
