Use the gradient and one point equation and rearrange into the form
Explanation:
The equation of a line can be found if the gradient or 'slope' and one point on the line is know can be found with the equation:
Substituing in the values for your case we get:
Cleanining up the two negatives and expanding the brackets on the right hand side we get:
Now we take away 3 from both sides to get it in the form
This results in the equation and answer to your question:
