Visit http://www.3minutemaths.co.uk for quick reminder High School GCSE mathematics videos.

This video is all about proving the equation of a straight line x - 2y =10, is a tangent to the circle x^2 + y^2 =20. (xsquared + ysquared = 20).

The question might be on a GCSE maths non calculator paper and is around grade 7+.

It’s useful to draw the question first to try to understand what they are asking :-)


I hope the video helps and please do leave a comment - thanks!
