Question

If you help me I will medal, and you will help me from failing lol
What is the slope for the line tangent to the circle x2 + y2 = 8 at the point (2, -2)?

Answer 1

ok... start by drawing a diagram

so the centre of the circle is (0,0)

so find the slope of the line segment from (0, 0) to (2,-2) (the radius)

the tangent is perpendicular to the radius

so then find the the negative reciprocal of the radius line segment,

hope that helps
