# Express X-Y intercept line equation with Latex ?

jojoba26 shared this question 11 years ago

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

x-1　　 y-3

－－－ = －－－ (for example) is considered OK

0　　　　5

simply we explain to student that 0 in denominator means 0 for numerator (in this case x-1=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

Thank you

I modify it, and the denominator is no longer 0

:confused:
