If: y = 2x then y^2 = 4x^2
If: x^2 +y^2 -8x -y +5 = 0 then x^2 +4x^2 -8x -2x +5 = 0
Collecting like terms: 5x^2 -10x +5 = 0
Dividing all terms by 5: x^2 -2x +1 = 0
Factorizing the above: (x -1)(x -1) = 0 meaning x = 1
By substitution into the original equation contact is made at: (1, 2)

What is the definition of a tangent line?
A tangent is a line that just touches a curve at a single point and its gradient equals the rate of change of the curve at that point.
What is meant by tangent to a curve at a point?
It is a straight line that touches the curve such that the line is perpendicular to the radius of the curve at the point of contact.
What does a Tangent look like?
Usually a straight line that touches a curve at one point. At the point of contact, the tangent is perpendicular to the radius of curvature.
How do you find the point of tangency?
A tangent is an object, like a line, which touches a curve. The tangent only touches the curve at one point. That point is called the point of tangency. The tangent does not intersect (pass through) the curve.
What is the name given to a straight line that touches a curve?
In geometry a straight line that touches a curve is called a tangent.

What is the tangent of the curve?
A tangent is a line which touches, but does not cross, a curved line.
