Please help me understand this tangent/parametric curve problem

Ok, so we the question gives two finctions x(t) and y(t) and asks for the equation of the tangent line at t = 1.

I found the slope by evaluating dy/dx at 1, but how do I find the y-intercept?

Can't you use the point (x(1),y(1)) to solve for the intercept?

yes, I can !
