The ordered pair (–8, –24) is a solution of the equation y = 3x.
no
Apologies for the error. The ordered pair (–8, –24) is not a solution of the equation y = 3x.
The correct ordered pair that is a solution of the equation y = 3x is (–2, –6).
The correct ordered pair that is a solution of the equation y = 3x is (–2, –6).
