You can put this solution on YOUR website!
3x+2y+4=0
:
if x=-2 as in your first ordered pair
:
3(-2)+2y+4=0
:
-6+4+2y=0
:
2y=2
:
y=1...........so we have an ordered pair of (-2,1) not (-2,0)
:
for x=0 in (0,-3)
:
3(0)+2y+4=0
:
0+2y+4=0
:
2y=-4
:
y=-2.................so the ordered pair for x=0 is (0,-2)
:
:
and for x=2 it should be (2,-5)
