Question

which of these ordered pairs is a solution to this equation? y = 4x - 7 (7, 11) (4, 9)

Explanation:

Step1: Test (7,11)

Substitute \( x = 7 \), \( y = 11 \) into \( y = 4x - 7 \).
Right - hand side: \( 4\times7 - 7=28 - 7 = 21 \).
Left - hand side: \( 11 \). Since \( 11
eq21 \), (7,11) is not a solution.

Step2: Test (4,9)

Substitute \( x = 4 \), \( y = 9 \) into \( y = 4x - 7 \).
Right - hand side: \( 4\times4 - 7 = 16-7=9 \).
Left - hand side: \( 9 \). Since \( 9 = 9 \), (4,9) is a solution.

Answer:

(4, 9)
