Question

Find the slope of the tangent line.

Answer 1

A circle is centered at the point (6,0) and has a radius 5. Find the slope of the line passing through the point (-7/3,0) and tangent to the upper half of the circle.

Answer 2

\[x^{2} + y^{2} = 5^{2}\]

Answer 3

\[y = \sqrt{25 - (x-a)^{2} }\]
