For this we will use equation that gives us equation of line that goes through 2 given points.

that equation is:
 y - y1= \frac{y2 - y1}{x2 - x1} (x - x1)

now we implement our given coordinates.
let Q be point 1 and R be point 2
y - 1 = 6/2(x - 0)
y - 1 = 3x

Answer is b.

Suppose the real exchange rate is 3/4 gallon of country A's gasoline per gallon of U.S. gasoline, a gallon of U.S. gasoline cost
olchik [2.2K]
The nominal exchange rate (NER) is given by:

NER = RER × (foreign price / US price)
        = 3/4 × ( 6 / 3)
        = 3/2

In fact, with 1$ you can buy 1/3 of a US gallon, which corresponds to 1/4 of a foreigner gallon, which you would pay 3/2units.

Hence, the correct answer is a) <span>3/2 units of country A's currency per dollar.</span>
