1.Find the equation of both lines that pass through the point (-2,4) and are tangent to the the parabola y=-x^2 -1. Show all work.

2. Find the point on the curve $\displaystyle y={\sqrt{x} +3}$ where the tangent line is perpendicular to the line 6x+y-5=0.

Can someone help me with this please and list the steps in solving this problem.
