b.
1) x+y=2
2) -y=-3x
x = 1/2
y = 3/2

Please graph the given equations and list the number of solutions for each system and why?
a.
1) x+y=5
2) x-y=1
it has 1 solutions since the lines intersect

b.
1) 2x+y=5
2) y=-2x+5
has infinite number of solutions since the two lines are the same

c.
1) y=2x+1
2) y=2x-2
has no solutions since the lines do not intersect (they are parallel)
