# Find the Point on The X-axis Which is Equidistant from (2, - 5) and (- 2, 9). - Mathematics

Find the point on the x-axis which is equidistant from (2, - 5) and (- 2, 9).

#### Solution

We have to find a point on x-axis. Therefore, its y-coordinate will be 0.

Let the point on x-axis be (x,0)

Distance between (x,0) and (2.-5) = sqrt((x-2)^2+(0-(-5))^2) = sqrt((x-2)^2+(5)^2)

Distance between (x,0) and (-2.-9) =sqrt((x-(-2))^2+(0-(-9))^2) = sqrt((x+2)^2+(9)^2)

By the given condition, these distances are equal in measure.

sqrt((x-2)^2 +(5)^2) = sqrt((x+2)^2+(9)^2)

(x-2)2+25=(x+2)2 + 81

x2 + 4-4x +25 = x2+4+4x+81

8x = 25-81

8x = -56

x =-7

Therefore, the point is (− 7, 0).
