Answer:
A. 4
Step-by-step explanation:
g(x) has an even steeper, positive slope. The only answer could be A
{ 2 x + 4 y = 12
y = 0.25 x -3
Arrange equation variables of elimination :
{ 2 x + 4 y = 12
-0.25 x + y = - 3
Multiply ( -0.25 x +y = - 3 ) by 8 :
8y - 2 x = - 24
{ 2 x + 4y = 12
-2x + 8y = -24
----------------------
12 y = -12
y = - 12 / 12
y = - 1
For x :
2 x + 4y = 12
2 x + 4 ( - 1 ) = 12
2 x - 4 = 12
2 x = 12 + 4
2 x = 16
x = 16 / 2
x = 8
x = 8 and y = - 1 => ( 8 , - 1 )
