Final answer:
The solution to the inequality y < 2/3x is option 3) (3, 5).
Step-by-step explanation:
To determine which of the given options is a solution to the inequality y < 2/3x, we need to substitute the values of x and y into the inequality and check if it holds true.
Option 1: (0, 3)
3 < 2/3*0
3 < 0
False
Option 2: (-3, 1)
1 < 2/3*(-3)
1 < -2
False
Option 3: (3, 5)
5 < 2/3*3
5 < 2
True
Option 4: (1, 2)
2 < 2/3*1
2 < 2/3
False
Therefore, the only solution to the inequality is option 3) (3, 5).
