<PRE><B>Question 335495</B>
Solve the systems of equations by graphing.Then Classify the system.
3x-9y=72
2x-6y=-12
-----------------
Simplify each equation:
x - 3y = 24
x - 3y = -6
-------------------
Put in slope-intercept form:
y = (1/3)x - 8
y = (1/3)x +2
-------
Graph:
{{{graph(400,300,-10,10,-10,10,(1/3)x-8,(1/3)x+2)}}}
---------------------------------
The lines are parallel.
The system is said to be inconsistent because there
is no (x,y) pair that satisfies both equations.
