Question

What is an equation of the line tangent to the circle x2+y2=32 at (4, 4)

Answer 1

Explanation:

Center is at (0, 0) for circle you need to find the slope from center to point so that you can find perpendicular slope.

slope = (4-0)/(4-0) =1

the perpendicular slope needs to be flipped and opposite sign

m(tan)= -1 point for tan = (4,4) put in point-slope form

y-4= -1(x-4)

y-4 =-1x+4

y = -x +8

Answer 2

y=x+8

Explanation:

The answer is y=x+8
