1. Find the equation of the line joining the points ( 5,1) and (-7,-7) ( 5 marks)
--------
Step 1, find the slope, m
Step 2, use y-y1 = m*(x-x1) where (x1,y1) is either point.
====================
2. Find the equation of the line passing through the point (2,1) and perpendicular to the line 2y = 7 � x
----
Find the slope of the given line.
The slope of lines perpendicular is the negative inverse of the slope of the given line.
