a circle is tangent to the y-axis at y=3 and has one x-intercept at x=1
1. determine the other x-intercept
2. find an equation for the circle

so i know two points on the circle are (0,3) and (1,0) and the equation for a circle is (x-a)^2 + (y-b)^2 = r^2 but i don't know how to solve the two questions
