Question

To determine if an ordered pair is a solution to a system of linear equations in two variables, __________.
A.
substitute the coordinates of the ordered pair into either equation to see if it produces a true statement
B.
substitute the coordinates of the ordered pair in both equations to see if it produces a true statement for each
C.
substitute the coordinates of the ordered pair in the first equation to see if it produces a true statement
D.
substitute the coordinates of the ordered pair in the second equation to see if it produces a true statement

Answer 1

B. You must make sure the solution (as a coordinate point) works for both equations.
