Question

Choose the system of equations which matches the following graph:

Question 11 options:


1)

x − 2y = 8

2x + 4y = 12


2)

x − 2y = 8

2x − 4y = 12


3)

x + 2y = 8

2x + 4y = 12


4)

x + 2y = 8

2x − 4y = 12


Thanks for helping me!

Answer 1

3

Explanation:

the equations of the lines are y= -1/2x+3(red) and y= -1/2x+4(blue)

rearrange the equations to find a match

1. y= -1/2x+ 4

y= -1/2x+3

2. y= 1/2x+4

y= 1/2x+3

3. y= -1/2x+4

y= -1/2x+3

4. y= -1/2+4

y= 1/2x-3
