How Do You Find the Line of Symmetry for Isosceles Triangle ABC?

[mark123]

ABC is an isosceles triangle such that
AB=AC
A has coordinates (4,37)
B and C lie on the line with equation 3y=2x+12

Find an equation of the line of symmetry of triangle ABC Give your answer in the form px + qy = r where p,q and r

I've requested that this be moved to homework. In any case, before we can help you need to show how much of the problem you can do yourself.

@mark123 -- please show your work on this problem so that we can then provide tutorial help. We are not allowed to help you until you show your work. Thank you.

The line of symmetry of an isosceles triangle is always perpendicular to the base. Find the line through (4, 37) and perpendicular to 3y= 2x+ 12.
