The ordinate is the xvalue and the abscissa is the yvalue so yo fond the point or points where they are equal set $y = x$ in the equation to get $x=(4x^2)^{1/2},$ square both sides and solve for $x.$ Check to see that for any value of $x$ you found that $x=(4x^2)^{1/2}.$ Now find the slope of the tangent to the curve at these point(s).
