Which of the following best describes the relationship between the graphs of the equations in this system?
y = 2x - 6
y = -2x + 6
The lines intersect at the point (0, -3).
The lines intersect at the point (3, 0).
The lines do not intersect because their slopes are opposites and their y-intercepts are opposites.
They are the same line because their slopes are opposites and their y-intercepts are opposites.

Solve the system:
-4x + 7y = 26
4x + 7y = 2
x = -3, y = 2
x = 3, y = -2
x = -2, y = 3
x = 2, y = -3

Which of the following describes the solution set of this system?
y = 0.5x + 7
y = 0.5x - 1
The solution is (-2, -3) because the graphs of the two equations intersect at that point.
The solution is (0.5, 3) because the graphs of the two equations intersect at that point.
There is no solution because the graphs of the two equations are parallel lines.
There are infinitely many solutions because the graphs of the two equations are the same line.
