\(ABCD\) is a rectangle.
\(A\), \(E\) and \(B\) are points on the straight line L with equation \(x + 2y = 12\)
\(A\) and \(D\) are points on the straight line M.
\(AE = EB\)
Find an equation for M. (4)
| Answer | Mark | Notes |
|---|---|---|
| \(y = 2x + 36\) | P1 | starts process, eg by rearranging to find gradient, eg \(y = 6 - \dfrac{x}{2}\) or \(\dfrac{-1}{2}\) or positions of \(B\) and \(E\) |
| P1 | complete process to find position of \(A\) or uses \(\dfrac{-1}{m}\) to find the gradient of M | |
| P1 | complete process to find equation of M | |
| A1 | \(y = 2x + 36\) oe |
