• I, II, and III

• II, III, and IV

Which of the following equations can be paired with 𝑥 + 2𝑦 = 8 to make a consistent and independent system of equations?

• −3𝑥 − 6𝑦 = −24

• 7𝑥 + 14𝑦 = −16

• 3𝑥 − 2𝑦 = 4

• 2𝑥 + 4𝑦 = 16

Which of the following equations can be paired with 3𝑥 − 2𝑦 = 5 to make a consistent and dependent system of equations?

• −15x + 10y = −25

• 6x − 4y = −10

• x + 2y = 1

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.
