## Algebra 1: Common Core (15th Edition)

In order to see if something is a solution to an equation, we plug in the (x,y) point to see if the equality is correct. Thus, we plug (-6,0) into $y=-2(x+3)$ to find: $0=-2(-6+3)$ $0=-2(-3)$ $0=6$ 6 does not equal 0, so this is not a solution to the equation.
