@lucyv7129 first read the question properly..

Answer 5

So it would be 5?

Answer 6

No, follow what Water is saying.

Answer 7

it would be c

Answer 8

if u sub in the coordinates for c, it gives u 5, which is the answer

Answer 9

@waterineyes o_0 don't lecture me...

Answer 10

For example, just put A option in the given equation 2x + y = 5..

Option A is (2, -1)

So here x = 2 and y = -1..

Just put these values in 2x + y and check whether it is giving you 5 or not??

for example, first one I am doing it for you..

\[2x + y\]
\[2 \color{red}{(2)} + \color{red}{(-1)} \implies 4 - 1 = 3\neq 5\]

Answer 11

So, Option A is wrong...

And just try for other options likewise for B, C and D... And check which will give you 5..
