What is the slope of any line perpendicular to the line passing through #(2,2)# and #(9,5)#?
the slope of the line passing through the given pts is
negative inverse of this slope will be the slope of the line perpendicular to the line joining the given pts.
Hence the slope is
The gradient of the perpendicular line is
The standard form equation for a straight line graph is:
Then it follows that
Given that the first line had gradient
and that the gradient of the perpendicular line is
Then we have:
