Answer:
USD/CHF is the currency pair, where USD stands for United States Dollar, and CHF stands for Swiss Francs.
This currency pair shows how many Swiss Francs are needed to buy 1 US Dollar. <em>The first currency listed is called base currency, and the second currency is called the quote currency. </em>Basically, the ratio shows how much of the quote currency is needed to purchase one unit of the base currency.
The ration of this pair is which means that we need 1.4481 CHF to buy one dollar.
It is a bit tedious to write 6 equations, but it is a straightforward process to substitute the given point values into the form provided.
For segment ab. (x1, y1) = (1, 1); (x2, y2) = (3, 4).
... x = 1 + t(3-1)
... y = 1 + t(4-1)
ab = {x=1+2t, y=1+3t}
For segment bc. (x1, y1) = (3, 4); (x2, y2) = (1, 7).
... x = 3 + t(1-3)
... y = 4 + t(7-4)
bc = {x=3-2t, y=4+3t}
For segment ca. (x1, y1) = (1, 7); (x2, y2) = (1, 1).
... x = 1 + t(1-1)
... y = 7 + t(1-7)
ca = {x=1, y=7-6t}
