Find the equation of the locus of a point which moves so that the sum of its distances from the points (2,1) and (8,1) is 10
----------
The distance from P(x,y) to (2,1) = sqrt((x-2)^2 + (y-1)^2)
The distance from P(x,y) to (8,1) = sqrt((x-8)^2 + (y-1)^2)

sqrt%28%28x-2%29%5E2+%2B+%28y-1%29%5E2%29+%2B+sqrt%28%28x-8%29%5E2+%2B+%28y-1%29%5E2%29+=+10
