Algebra.Com's Answer #692999 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! formula for circle at this point is y=-sqrt (8-x^2) \n" ); document.write( "The derivative is -2x/-2 sqrt(8-x^2); when x=2, derivative equals 2/sqrt(4)=1, so the slope is 1 \n" ); document.write( " |
