Coordinate Geometry (OCR GCSE Maths: Higher): Exam Questions

Here are the equations of four straight lines.

Line A   y = 2x + 4
Line B   2y = x + 4
Line C   2x + 2y = 4
Line D   2x – y = 4

Two of these lines are parallel.

Write down the two parallel lines?

$P$ is the point (2, 14)
$Q$ is the point (6, 8)
$R$is the point (2, 5)

Use gradients to show that angle $PQR$ is not a right angle.

$A$ is the point (2, –5)

$B$ is the point (4, –9)

Show that the gradient of the straight line passing through $A$ and $B$ is –2

$C$ is the point (–301, 601)

Does $C$lie on the straight line passing through $A$and $B$?

You must show your working.

Point $P$ has coordinates (5, 7).
Point $M$ has coordinates (1, 2.5).

Point $M$ is the midpoint of the line $PQ$.

Find the coordinates of point $Q$.

$\mathbf{A}$ and $\mathbf{B}$ are straight lines.
