implicitly defined parametrizations

[lunarskull]

assuming that the equations in excersise 14 define x and y implicitily as differentiable functions x=f(t), y=g(t), find the slope of the curve x=f(t), y=g(t) at the given value of t.

14. x=(5-(square root of t))^1/2, y(t-1)=ln y, t=1


plz help

Chain rule:
dy/dx = (dy/dt)/(dx/dt)
