pts2 is your friend the Line! In 2D, any equation of the form a*x+b*y + c = 0 has solutions namely the x and y coordinates that satisfy the identity, namely lhs = rhs, line up along a fixed line specified by the three constants a, b and c.

hs = x-3;
rhs = 17*y+9;

lhs = lhs -9;
rhs = rhs -9;

lhs = lhs/17;
rhs = rhs/17;

show lhs also rhs;
