The slope, m, of a line is defined as . So just substitute your ordered pairs into that equation to get , which simplifies to which reduces to m=-1. That means our equation is y=-x+b in slope intercept form. To find out what b is, substitute one of the ordered pairs. Taking (-1,3) gives us 3=1+b, which reduces to b=2. So our final equation is y=-x+2 and graphs to:
