This one should be quite easy to answer because we already have the value of x. (x = 1) all we have to do is find the y-value and where it is on the number line.
The answer is d.42 because since the denominator(8) is being multiply by 6 to get 48, you should multiply 7 by 6 too to get the answer 42. And so the answer is 42/48.
