Given:
Leo line perpendicular to the line shown
Line pass (F,G)
Grid line,
Find-:
Equation of Leo's line.
Explanation-:
Slope of grid line is:

Where,

Choose any two point

Then slope is:

Slope of perpendicular line is:

So the equation of Leo's line is:

Line pass (F,G) then,

So, equation of line is:
