what is the problem you are trying to solve? Its hard to help without knowing what need to be solved

Answer 3

How do you solve equidistant in this question?

Answer 4

which one, the\[d ^{2}=(x+2)^{2}+4(y-4)^2\]?

Answer 5

for (1,-1) and (-1,1), the equation of the line is y =-x. Hence the perpendicular line passes through those point is y =x. All points on this line is equidistant (1,-1) and (-1,1)
