isn't a circle. Write it properly.
Plug these points in and find a, b and r.
Use implicit differentiation. Or write the circle as two functions of x, then use one of them and find the slope. Then use the point given to find the equation.
Could someone show me how to work out these please
1. The circle x^2(y+3)^2=25 meets the x axis at p and q, find the coordinates of p and q?
2. The points A(7,4) B(8,-7) and C(-4,3) lie on a circle. Find the equation of the circle?
3. Find the equation of the tangent at the point (3,1) on the circle
x^2+y^2-4x+10y-8=0
Thanks for your help

Hello, Colin!
On a hunch, I found the slopes of the sides of this triangle.2. The points lie on a circle.
Find the equation of the circle.
Hence: .
The center is the midpoint of the hypotenuse
. . Center: .
The radius is the length of (or or ).
. .
The equation is: .
