(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Find the point on the curve y=x^2 that is closest to the point (18,0)

2. Relevant equations

y=x^2

3. The attempt at a solution

so, dy/dy=2y

Then I tried to use the fact that the product of 2 straight lines that meet at right angles is -1 to come up with a formula for a straight line through (18,0) that meets at a tangent to the closest point of the curve but can't seem to get this to work.

Am i barking up the wrong tree here?

Any help appreciated
