#1: (3, 4) T; (2, -1) E; (1, -4) O; (0, -5) U; (-1, -4) T; (-2, -1) M; (-3, 4) S; #2: (1, 5) T; (0, 0) E; (-1, -3) H; (-2, -4) N; (-3, -3) T; (-4, 0) S; (-5, 5) D; #3: (-5, 8) O; (-4, 1) E; (-3, -4) I; (-2, -7) K; (-1, -8) Y; (0, -7) A; (1, -4) E; (2, 5) L; (3, 8) S; #4: (4, 11) E; (3, 1) L; (2, -5) D; (1, -7) T; (0, -5) C; (-1, 1) K; (-2, 11) S
Explanation:
To find the y-coordinate of each ordered pair, you substitute the value for the x-coordinate into x in the equation.
For example, on #1, substitute 1 in for x:
y = 3² - 5 = 9 - 5 = 4
This means the ordered pair is (3, 4) and corresponds with T.
In the same problem, substitute 2 in for x on the next line down:
y = 2² - 5 = 4 - 5 = -1
This means the ordered pair (2, -1) corresponds with E.
Continue this process to get all of the answers.
