Question

The graph of a system of equations is shown. What is a reasonable estimate of the solution?

Answer 1

C

Explanation:

Firstly, let's look at the x of the interception. Clearly, we can see the point locates between 3 and 4. Therefore, choices A and B could be crossed out, which left only C and D.

Next, we look at the y of the interception. We can see that the point locate a bit higher than 7
`(1)/(2)`. Therefore, the only available answer is

7
`(2)/(3)`.

Therefore, the correct choice is C.

Hope it helps.
