Final answer:
To find a solution to the equation "-x + 5y = 7," we can substitute the given values of x and y into the equation and check if it satisfies the equation. The ordered pair (x, y) that is a solution to the equation is (-2, -1).
Step-by-step explanation:
To find an ordered pair (x, y) that is a solution to the equation "-x + 5y = 7," we can substitute the given values of x and y into the equation and check if it satisfies the equation.
a) (3, 2): -3 + 5(2) = 7. This is not true, so (3, 2) is not a solution.
b) (-2, -1): -(-2) + 5(-1) = 7. This is true, so (-2, -1) is a solution.
c) (1, 2): -(1) + 5(2) = 7. This is not true, so (1, 2) is not a solution.
d) (-1, 2): -(-1) + 5(2) = 7. This is true, so (-1, 2) is a solution.
Therefore, the ordered pair (x, y) that is a solution to the equation is (-2, -1).
