Answer:
2x + 2y = 4 does not belong
Step-by-step explanation:
2x + y = 4 → <u>y = -2x + 4</u>
y = -2x + 4 → <u>y = -2x + 4</u>
f(x) = -2x + 4 → <u>y = -2x + 4</u>
2x + 2y = 4 → <u>y = -x + 2</u>

Answer:
Step-by-step explanation:
Answer:
Option b is the correct answer as both the equations are true for given solution.
Step-by-step explanation:
Given equations are:
-0.1x-0.3y=1.2
0.2x-0.5y=2
We can observe each graph and find the point that is the solution and put the point in the equations to know if that point is the solution
<u>For option A:</u>
(0,4)
Putting x=0 and y = 4 in both equations

This is not the correct answer as both equations are not true with this solution
<u>For Option B:</u>
(0,-4)
Putting x = 0 and y = -4 in both equations

Both equations are true for (0,-4) hence it is the solution of the system.
<u>For Option C:</u>
(4,0)

Not true for both equations
Hence,
Option b is the correct answer.
Well, put x=0 then y=4
x=6 y=0
x=3 y=2
Now plot the graph :)
