Answer:
y = 3x equation represent direct proportion.
Step-by-step explanation:
Direct Proportion:
If x value increases then y value also increases. This is called direct variation or y is directly proportional to x.
For y = 3x
x = 1 , then y = 3
x = 2 , then y = 6
So on, here x is increasing then y is also increases.
Hence, y = 3x equation represent direct proportion.
Inverse Proportion:
If x value increases then y value decreases. This is called indirect variation or y is inversely proportional to x.
For y = -2x + 1
x = 1 , then y = -1
x = 2 , then y = -3
So on, here x is increasing then y decreases.
Hence y = -2x + 1 is Indirect variation.
