Question 175247: It says classify each system and give the # of solutions but i cant get it. The problem is 3x=-y-2 and 2y+4=-6x. It is solving special Systems Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! It says classify each system and give the # of solutions but i cant get it. The problem is 3x=-y-2 and 2y+4=-6x
----------------------
Put each equation in slope-intercept form.
y = 3x-2
y = -3x -2
-----------------
The slopes are 3 and -3. Since they a different the
lines must intersect at a single point.
----------
The system is said to be consistent and it has one
Real.
-------------
Note:
If the slopes are the same and the intercepts are the
same, the system is dependent and has an infinite number
of solutions.
If the slopes are the same and the intercepts are different,
the system is inconsistent and has no solution.
