question 3
to enter an ordered pair, enter the x and y coordinates, enclosed in parentheses and separated by commas.
enter the coordinates (10,7):
to enter several ordered pairs, you must separate them by commas.
which of the following is the correct format for entering two sets of coordinates?
(10,7,7,1)
10,7,7,1
(10,7),(7,1)
(10,7)(7,1)

Explanation:

An ordered pair is written in the form \((x,y)\). When entering multiple ordered pairs, they should be separated by commas.

• Option \((10,7,7,1)\) is incorrect as it combines two ordered pairs into one without proper separation.
• Option \([10,7,7,1]\) uses square brackets which are not the standard notation for ordered pairs (parentheses are used for ordered pairs in coordinate - related contexts).
• Option \((10,7)\ (7,1)\) has a space instead of a comma for separation.
• Option \((10,7),(7,1)\) correctly uses parentheses for each ordered pair and a comma for separation.

Answer:

\((10,7),(7,1)\)
