Perpendicular Bisector
Please help:
The perpendicular bisector of the line segment AB is 10x + 4y = 25. If A has coordinates (2,-6), calculate the coordinates of B.

What is the relationship between the gradients of perpendicular lines?
What is the gradient of 10x+4y=25?
What is the gradient of AB?
Or did you have all that already?
There's still more to do of course.

for the gradient of the equation I have -5/2. But for AB I have no gradient and have no idea where to go from here.

The gradient will be the negative reciprocal?
