Q: Find the coordinates of all points on the graph of

at which the tangent line passes through the point

__My solution so far:__
What I understood is that there is a point on outside the parabola/ curve

and another point is on the curve which is unknown and need to figure out

and they are connected through a tangent line.

Now first let me figure out the derivative/slope of the tangent line over that curve.

{ is y always equals f(x)? maybe this is only when y is function of x right?}

So now we know the slope of the tangent line

we know 2 co-ordinates of one end

and need to figure out the other end

.

and we can use the slope formula here

**CORRECT**
