using the point-slope form of the line: y - y_1 = m(x - x_1) to find the equation of the line passing through the points (5, -3) and (-1, 5)
See the PurpleMath article, you need the second worked example.

Oooh, I'd like to answer this as we just learned it yesterday .
To get the equation of a line passing through two points, you need to know how to work out the gradient:
or:
So to work that out with your question:
So you now have the gradient, . Now choose one of the coordinates, I'll use .
I've checked that against both of your coordinates and it works, so look over those notes and you should be able to understand it .
