Which of the following ordered pair satisfies the given system

• (7,4)

• (−7, −4)

• (7, −4)

• (−7, 4)

Jayda was tasked by her teacher to verify if the ordered pair (−1, 2) will satisfy to the system. Is her solution correct

• Yes, because she substituted the values of the variable x = 1and 𝑦 = -2.

• Yes, because she followed the process of evaluating the system of linear equations.

• No, because the point (-1, 2) is not a common point of the given system of linear equations in two variables.

• No, because she is supposed to make two false statements that makes a solution of the system of linear equations.
