Question 2 • College Readiness Mathematics

Which graph represents the same relation as the set start set open paren negative 3 comma 2 close paren comma open paren 5 comma 5 close paren comma open paren 3 comma 3 close paren comma open paren 3 comma negative 2 close paren end set ?

Answer
A
Image with description A coordinate plane with x-axis from negative 5 to 5, y-axis from negative 5 to 5, has 4 points. The points are (negative 3 comma 2), (3 comma negative 2), (3 comma 3), (5 comma 5).
B
Image with description A coordinate plane with x-axis from negative 5 to 5, y-axis from negative 5 to 5, has 3 points. The points are (negative 3 comma 2), (3 comma negative 2), (5 comma 5).
C
Image with description A coordinate plane with x-axis from negative 5 to 5 comma y-axis from negative 5 to 5 comma has 4 points. The points are (negative 2 comma 3), (2 comma negative 3), (3 comma 3),(5 comma 5).
D
Image with description A coordinate plane with x-axis from negative 5 to 5, y-axis from negative 5 to 5, has 7 points. The points are (negative 3 comma 0), (0 comma 5), (0 comma 3), (0 comma 2), (0 comma negative 2), (3 comma 0), (5 comma 0).

Explanation

A relation written as ordered pairs is graphed by plotting each pair as an (x, y) point. The set contains (−3, 2), (5, 5), (3, 3), and (3, −2), and choice A shows exactly those four points. Choice B is missing (3, 3), while the points in C have some coordinates reversed.
