core 1 maths help?
Sketch the following circle:
x^2+y^2-3x-10y=0
The answer on the back of the book says that the centre is ( 1 1/2,5) passes through the origin.
I got the centre bit but i dont get how you could work out if the equation of the circle passes through the centre or not??
x^2+y^2-3x-10y=0

To show that the circle passes through the origin (0,0), you just need to substitute in x = 0 and y = 0 into the equation x^2+y^2-3x-10y=0 and show that it is satisfied.
