Given two points, and , you can write the equation of the line using the two-point form of the equation of a line:

y+-+y%5B1%5D+=+%28%28y%5B1%5D+-+y%5B2%5D%29%2F%28x%5B1%5D+-+x%5B2%5D%29%29%28x+-+x%5B1%5D%29. Just insert the values from the two ordered pairs and do the arithmetic.

Once you have simplified things, solve the equation for y (that is, manipulate the equation so that y is by itself on the left and everything else is on the right) to put the equation in slope-intercept form.
