Ordered Pairs That Are Solutions to Linear Equations

Consider the system of linear equations 2x + 3y = 8 and 3x + y = –2. Which statement is correct?

• The point (1, 2) is not a solution to the system of equations because it satisfies neither equation

• The point (1, 2) is not a solution to the system of equations because it does not satisfy the equation 3x + y = –2.

• The point (1, 2) is a solution to the system of equations because it satisfies the equation 2x + 3y = 8.

• The point (1, 2) is a solution to the system of equations because it satisfies both equations.

Betty correctly determined that the ordered pair (–3, 5) is a solution to the system of linear equations 6x+5y=7 and x+4y=17. Based on this information, which statement is correct?

• (–3, 5) satisfies neither the equation 6x + 5y = 7 nor the equation x + 4y = 17.

• (–3, 5) satisfies the equation 6x + 5y = 7 but not the equation x + 4y = 17.

• (–3, 5) satisfies the equation x + 4y = 17 but not the equation 6x + 5y = 7.

• (–3, 5) satisfies both the equation 6x + 5y = 7 and the equation x + 4y = 17.
