Please I need help, its for my homework

**Reiny**, Thursday, January 31, 2013 at 9:54amDid you notice that your first two lines are parallel ?

so if our circle touches both of those, it must have its centre on x+2y = 3.

now you have the question:

a circle has its centre on x + 2y = 3 and is tangent to y=2x-5 or 2x - y - 5 = 0

and it is the same question as the one I answered for you on Tuesday
