Answer:
C none of the above
Step-by-step explanation:
x + z + y
is not going to be equal to x + y - z
Its like saying 10 + 5 - 4 = 11
To 10 + 5 + 4, they are not going to be equal
2/5x+y=3
-2/5x -2/5x
y=-2/5x+3
Does y = to whole number or just like that? if it Whole number I will solve it tell me
Answer:

Step-by-step explanation:
Slope-intercept form: y = mx + b
The line intersect Y-axis at y=0 so b = 0
The line passses through points (0, 0) and (2, -1), so the slope:

Therefore the equation:
