anonymous · Answer

The points are in the format : $(x, f(x))$, so first value is $x$ and other value is $f(x)$..

anonymous · Answer

One by one, put $x$ and $f(x)$value from the options in the expression given to you, and check whether you get the equation satisfied or not..

anonymous · Answer

Like I try your first option: There $x = -2$ and $f(x) = -1$, put these values in the expression given:
$$-1 = 3- 2(-2) \ -1 = 3 + 4 \ -1 \ne 7$$

anonymous · Answer

so three and five are correct?

anonymous · Answer

So, option 1 is not satisfying the equation..
