Find the equation of the tangent to find the x and y intercepts of the line.
With the coordinates, find the coordinates of the midpoint
Derive a parametric equation for the mid point and solve for the cartesian equation.
Check with GC.

hi! I am able to solve till the mid point. But I don't know what to do with the mid point. In your answer (last picture), where did the y² come from and why y²?
hey! so basically the mid point coordinates will be following the two parametric equations as seen in the picture, the x and y coordinates.
the y^2 is just a method to fit them into a cartesian equation
