In this video we discover the equation of a circle, thanks to how it looks on a graph. The equation of a circle is (x - a)^2 + (y - b)^2 = r^2, where (a, b) is the centre of the circle and r is the radius. The coordinates of the centre point (a, b) are in the brackets with the x and y, but you just need to remember to change the sign of (a, b). We will look at how to find the equation of a tangent to a circle in another video.

Equations are used everywhere: in computers, business, internet searches, medicine to name a few examples. Which is why we study them a lot in Maths.
We have names to describe the different parts: coefficients, variables, constants and exponents. A variable is a symbol for a number we don’t know y

In this video we are going to look at rearranging straight line equations to find the gradient and y-intercept. Straight lines follow the equation y=mx+c, where the m is the gradient and the c is the y-intercept. But straight line equations aren’t always written out in this nice form. Sometimes we h
