Use the formula:

\(\displaystyle \frac {y_{1}-y_{2}}{x_{1}-x_{2}} \)

Substitute values in to find the gradient.

Well you got (-3,5) and (4,3)

if you want to do y2-y1 then you must do x2-x1

if you want to do y1-y2 then you must do x1-x2

Ok,

when you are told to work out the gradient and you are given two points. Remember this formula:

\(\displaystyle \frac {y_{1}-y_{2}}{x_{1}-x_{2}}\)

You can also use:

\(\displaystyle \frac {y_{2}-y_{1}}{x_{2}-x_{1}}\)

They both will work.

Your question is: (-3,5) and (4,3)

In this case -3 will be \(\displaystyle x_{1}\) 5 will be \(\displaystyle x_{2}\). 4 will be \(\displaystyle y_{1}\) and 3 will be \(\displaystyle y_{2} \)

Now substitute the values into the formula.
