did u try to take the derivative?

this is a circle whose centre is at (0,0) and the slope of the radius to thE poinT (-4,-3) IS
-3/-4 = 3/4.
the tangent at this point is perpendicular to the radius so its slope will be -4/3

use the geearal form  y-y1 = m(x-x1)

where m = the above slope and (x1,y1)  = (-4,-3)
