Answer:
3. One Solution. (0,4). (they have different slopes and y-intercepts)
The solution can be found using elimination method:
Add the equations together
y = -x + 4
y = x - 4
2y = 0
y = 0
Solve for x
0 = x - 4
x = 4
(4, 0)
4. No solution
x + y = -2 and 3 which is not possible
The two lines would be parallel
