Graphing takes too long, substitution can sometimes complicate things quickly, therefore I would use elimination as my prime method of solving systems of equations.

Write the standard form of the equation of line through (3, -1) with a slope of -1.

kirill115 [55]

The standard form of a line: $Ax+By=C$ .

The point-slope form: $y-y_1=m(x-x_1)$

We have the point (3, -1) and the slope m = -1. Substitute:

$y-(-1)=-1(x-3)$

$y+1=-x+3$ <em>add x to both sides</em>

$x+y+1=3$ <em>subtract 1 from both sides</em>

$\boxed{x+y=2}$
