The answer is B because the domain is the x value, and because the lines have arrows they continue forever, meaning that they contain all real numbers.
Answer:
A. (2,5)
because 3×2 is 6, 6-1 is 5
so y=5
14x + 10y = 72
14x + 4y = 96
6y = -24
6 6
y = -4
14x + 10y = 72
14x + 10(-4) = 72
14x - 40 = 72
+ 40 + 40
14x = 112
14 14
x = 8
(x, y) = (8, -4)
