Quadratic Graphs

Quadratic graphs sound hard...but they're not really! They are simply just graphs in this format: y = x2 + anything To plot a quadratic graph just put in...
parallel lines

Parallel And Perpendicular Lines

Parallel LinesThese are just lines that have the same gradient. Above you will see the lines for y = 1.5x +1 and y = 1.5x - 0.5.It doesn't matter what the v...
straight line graph

y = mx + c

The standard way to arrange a straight line graph equation is y = mx + c is So if you are given an equation like this 4y - 8x = 5 then you should rearrange i...

Finding The Gradient

The gradient just measures how steep the graph is. The bigger the gradient, the steeper it is.You should learn the following formula:So let's take an example. ...
