Remember the formula for the gradient
`Gradient (m)=(y(chang\e\ i\n))/(x(chang\e\ i\n)`
You can remember the formula for the gradient as follows:
There is a large gradient on a mountain (m).
Put your friend's Y fronts over the eggs (y over x) to stop the eggs from cracking if you're going to roll your eggs down a mountain.
Large gradient is a mountain = m
Y fronts over the eggs = y over x
Or = `y/x`
Therefore `(m)=(y(chang\e\ i\n))/(x(chang\e\ i\n)`
To work out the gradient (m) of a line you divide the change in y by the change in x.
