i have two problems that i am having an immense about of difficulty on both of them include tangent lines in relation to a circle. the first question is:
For the circle x^2 + y^2 + 6x - 4y + 3 = 0, Find:
a) the center and radius
which i figured out is center (-3, 2) radius square root of 10
b) the equation of the tangent at (-2, 5) which i have no idea how to do
my other question is:
a circle is tangent to the y axis at y = 3 and has one x-intercept at x = 1.
a) determine the other x-intercept
b) deduce the equation of the circle
i don't know how to begin this one at all. thank you in advance for your assistance
