Question 569598: how many solutions does this system of equations have???
2x+3y=6
y=-2/3x-1
it woudd be amazing if you could answer soon! Found 2 solutions by Alan3354, TutorDelphia:Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! 2x+3y=6 --> y = (-2/3)x + 2
y=-2/3x-1
----------------
The 2 lines are parallel if you graph them.
No intersection, no solution.
You can put this solution on YOUR website! This has no solutions:
y=(-2/3)x-1 is already in slope intercept form
2x+3y=6
subtract 2x from both sides
3y=-2x+6
divide all by 3
y=(-2/3)x+2
Since these have the same slope but a different intercept they are parallel lines.
