Explanation Given information: The equation, y = 2 x − 1 and the ordered pairs ( − 3 , 4 ) and ( 0 , − 1 ) . Explanation: Consider the provided equation, y = 2 x − 1 Consider the first ordered pair ( − 3 , 4 ) . In the provided equation y = 2 x − 1 , substitute the values of x = − 3 and y = 4 . y = 2 x − 1 4 = 2 ( − 3 ) − 1 Perform multiplication and evaluate the expression as; 4 = 2 ( − 3 ) − 1 4 = − 6 − 1 4 ≠ − 7 This shows that the provided ordered pair ( − 3 , 4 ) does not result in a true statement. So, ( − 3 , 4 ) is not a solution to the equation y = 2 x − 1 as answered by Mark because on substitution of x = − 3 and y = 4 into the equation does not result in a true statement
