Rearranging Line Equations y = mx + c | Graphs | Maths | FuseSchool

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 have to do some rearranging. When straight line equations are written in the y = mx + c format, it easily tells us that the gradient is m and the y-intercept is c. Which is why it is often preferable to rearrange straight line equations to follow this format, and it also makes plotting the line much easier. You just need to recognise that any equation with an x and a y will be a diagonal straight line. It might also have a ‘c’ number on it’s own too. We then may want to rearrange the equation into the y = mx + c form as that’s much easier for comparing gradients and y-intercepts, and plotting the equation onto a graph.

What Are Vaccinations? | Health | Biology | FuseSchool

Vaccinations protect both humans and animals from a wide range of preventable and potentially serious illnesses. With vaccines, we take advantage of one of the most important aspects of the immune system: the ability to develop immunological memory. This means that once a person or animal is expose
