Answer:
is there a picture?
Step-by-step explanation:
Answer:
y=1, x=2
Step-by-step explanation:
x+y=3
x-y=1
Using elimination method
x-x+y--y=3-1
2y= 2
y=1
Substitute y=1 into equation 2
x-1=1
x=1+1
x=2
B. is the answer I believe since most are not functions
The x intercepts must be 1 and -4, so C.
