Question 487739: In substitution is your final answer a point?
Answer by richard1234(7193)   (Show Source):
You can put this solution on YOUR website! I have to make the intuitive guess that you are referring to solving a system of linear equations by substitution. If this is so, the answer is yes (most of the time), because a system of two linear equations of two variables will usually have one ordered pair as a solution. Graphically, all this is saying that two lines on the same plane meet at a point. The exceptions are when the lines are parallel (no solutions), or the lines are the same (infinitely many solutions).
