(y/(x+9y))= (x^2)-7

at the point (1, -6/55)

Use implicit differentiation to find the slope of the tangent line to the curve

  • Calculus - ,

    cross-multiply first

    y = x^3 - 7x + 9x^2y - 63y
    y' = 3x^2 - 7 + 9x^2y' + 18xy - 63y' , where y' = dy/dx

    64y' - 9x^2y' = 3x^2 + 18xy-7
    y' = dy/dx = (3x^2 + 18xy - 7)/(64 - 9x^2)

    I will leave it up to you to do the remaining arithmetic
