Question 457141
Can someone help me solve the system of equations by graphing? 
y= -x-12
4x - 3y= -13 
Are they consistent?
..
rewrite:
y+x=-12
-3y+4x=-13
..
3y+3x=-36 (times first equation by 3)
-3y+4x=-13
add
7x=-49
x=-7
y=-12-x=-12-(-7)=12-7=-5
point of intersection (-7,-5)
System is consistent
see graph below as visual check on answer
