The points P and Q have coordinates (-1, 6) and (9, 0) respectively. The line l is perpendicular to PQ and passes through the mid-point of PQ.
Find an equation for l, giving your answer in the form ax + by + c =0, where a, b and c are integers.

Step-by-step explanation:

Given

Required

The equation of l

First, calculate the slope (m) of PQ

Since l is perpendicular to PQ, the slope of l is:

Next, calculate the midpoint of PQ

The equation of l is:

Multiply through by 3

Open bracket

Rewrite as:

part d
