Express X-Y intercept line equation with Latex ?
Move point A alone X axis , or move point B alone Y axis
the line equation changes accordingly.
But as the point A move to (0,0), the line equation is :
－－－ + －－－ =1 (for example)
it is not correct.
Is it possible to combine "if " statement and Latex to avoid the situation.
any help will be appreciated!
