All the coordinates have equal values for \(x\) and \(y\). This is shown by the points on the line such as (10, 10) and (-4, -4). Graph A is \(y = -x\). All the coordinates have \(x\) and \(y ...

Before you start, it may be helpful to read the guide on coordinates and graphs from M1 and the guide on Pythagoras' theorem from M2. To find the midpoint of a line between two sets of coordinates ...
