Question

please help Graphs of Lines Assessment items Item 4 Which ordered pair is a solution to this equation? 2x + 3y = 16 (7, 2) (5, 2) (11, 1) (3, 2)

Answer 1

(5,2)

Explanation:

1) (7,2) means x=7, y=2

2x7+3x2 = 20 not 16 --> (7,2) not a solution

2) (5,2) means x=5,y=2

2x5+3x2 = 16 --> solution

3) (11,1)

2x11+3x1=25 not 16 ---> not a solution

4) (3,2)

2x3+3x2=12 not 16 ---> not a solution
