Respuesta :
y = x - 2.....its just a matter of subbing in ur points to see which ones are true.
(3,1)...x = 3 and y = 1
y = x - 2
1 = 3 - 2
1 = 1 (correct)
so ur solution is (3,1)
(3,1)...x = 3 and y = 1
y = x - 2
1 = 3 - 2
1 = 1 (correct)
so ur solution is (3,1)
Answer:
Option (a) is correct.
(3, 1) is the ordered pair that is the solution of the equation y = x - 2
Step-by-step explanation:
Given : equation y = x - 2
We have to find the ordered pair that is the solution of the equation y = x - 2
We will check each option one by one and see which satisfies the given equation.
Consider equation y = x - 2
a) (3, 1)
Put x = 3 and y = 1
LHS = 3 - 2 = 1 = y
b) (1, 3)
Put x = 1 and y = 3
LHS = 1 - 2 = -1 ≠ y
c) (-1, 3)
Put x = -1 and y = 3
LHS = -1 - 2 = -3 ≠ y
d) (3, -1)
Put x = 3 and y = -1
LHS = 3 - 2 = -3 ≠ y
Therefore, only (a) is correct.
