Answer:

Graphic 1: Not proportional

Graphic 2: Not proportional

Graphic 3: Proportional, y is 3/5 of x.

Explanation:

Graph 1: A parabola is not proportional.

Graph 2: When x = 1, y = 0. When x = 2, y = 2. When x = 3, y = 5. 5/3 is different of 2/2. So not proportional.

Graph 3:

When x = 5, y = 3. When x = 10, y = 6. 6/10 = 3/5. So proportional, y is 3/5 of x.
