Answer:
- Proportional, y = 3 times x
- Not proportional
Step-by-step explanation:
The graph shows a proportional relationship if it is a straight line that goes through the origin (0, 0). The constant of proportionality can be found by looking for the y-value when x = 1.
1) The graph is a straight line that goes through the origin. The relationship is proportional. When x=1, y=3, so ...
y = 3 times x
__
2) The graph does not go through the origin. The relationship is Not Proportional.
What you do is 20 divided by 4, which is 5. So then you times 32 by 5 and that's how you get 160.
