The coordinates of the 2 given points are W(-5, 2), and X(5, -4).
First, we find the midpoint M using the midpoint formula:
![\displaystyle{ M_{WX}= (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2} )= (\frac{-5+5}{2}, \frac{2+(-4)}{2} )=(0, -1).](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B%20M_%7BWX%7D%3D%20%28%5Cfrac%7Bx_1%2Bx_2%7D%7B2%7D%2C%20%20%5Cfrac%7By_1%2By_2%7D%7B2%7D%20%29%3D%20%20%28%5Cfrac%7B-5%2B5%7D%7B2%7D%2C%20%20%5Cfrac%7B2%2B%28-4%29%7D%7B2%7D%20%29%3D%280%2C%20-1%29.)
Nex, we find the slope of the line containing M, perpendicular to WX. We know that if
m and
n are the slopes of 2 parallel lines, then
mn=-1.
The slope of WX is
![\displaystyle{ m= \frac{y_2-y_1}{x_2-x_1}= \frac{2-(-4)}{-5-5}= \frac{6}{-10}= -\frac{3}{5}](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B%20m%3D%20%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%3D%20%5Cfrac%7B2-%28-4%29%7D%7B-5-5%7D%3D%20%5Cfrac%7B6%7D%7B-10%7D%3D%20-%5Cfrac%7B3%7D%7B5%7D%20%20%20%20)
.
Thus, the slope n of the perpendicular line is
![\displaystyle{ \frac{5}{3}](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B%20%20%5Cfrac%7B5%7D%7B3%7D%20)
.
The equation of the line with slope
![\displaystyle{ n= \frac{5}{3}](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B%20n%3D%20%5Cfrac%7B5%7D%7B3%7D%20)
containing the point M(0, -1) is given by:
![\displaystyle{ y-(-1)=\frac{5}{3}(x-0)](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B%20y-%28-1%29%3D%5Cfrac%7B5%7D%7B3%7D%28x-0%29)
![\displaystyle{ y+1= \frac{5}{3}x](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B%20y%2B1%3D%20%5Cfrac%7B5%7D%7B3%7Dx)
![\displaystyle{ 3y+3=5x](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B%203y%2B3%3D5x)
![\displaystyle{ 5x-3y-3=0](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B%205x-3y-3%3D0%20)
Answer: 5x-3y-3=0

Answer:
centre = (0, 0 ), radius = 5
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ( r is the radius )
x² + y² = 25 ← is in this form
with centre = (0, 0 ) and r =
= 5
