Express XY intercept line equation with Latex ?
Answered
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 :
x y
－－－ + －－－ =1 (for example)
0 5
it is not correct.
Is it possible to combine "if " statement and Latex to avoid the situation.
any help will be appreciated!

You could define another text for example T4="x=0" and then use the "if" statement
T5=If[x(A) == 0, T4, T1].
Then hide T1 and T4 and put T5 where you like.

hello
in spain the expression
x1 y3
－－－ = －－－ (for example) is considered OK
0 5
simply we explain to student that 0 in denominator means 0 for numerator (in this case x1=0)
in your case x=0 (your form do not let vertical line except x=0)
the position of number in geometry equations is understand only as a form for to get the data of a geometry figure not for to calculate with fractions
saludos
Thank you
I modify it, and the denominator is no longer 0
:confused:
