the graph shows the system of equations y=-x+6 and 3x+3y=18 ? Should the lines for the system be parallel?
1 answer
No, the lines for the system should not be parallel. The first equation has a slope of -1 and the second equation can be simplified to y = -x + 6, which also has a slope of -1. This means that the lines are not parallel and intersect at a single point.
