Please Help!! I will add more points for whoever answers correctly!!!
1. The ordered pair (-1, -1) is a solution of the system -4x + 2y = 2 and x + y = -2.
True or False
2. How many solutions exist for the system y = 2x + 5 and y = -0.2x - 4?
3. How many solutions exist for the system, x + y = 1 and y = -x + 1?
4. Solve the system.
y = x + 2 and y = -x + 0
