a. (1,1) b. (1,5) c. infinte number of solutions d. no solution

Answer 1

hi darth try graphing this with y=-x and y=6-x
if the 2 lines intersect, there will be a root or solution,,if not there wil be no solution...

Answer 2

by solving these two equations....
y=y...that is
-x=6-x or
-x+x=6 or
0=6

Answer 3

d is the answer here...no solution

Answer 4

x+y = 0
x+y = 6

no solution since they are parallel lines that never cross
