Answer:
The equation y = 20x is proportional ⇒ B
Step-by-step explanation:
Let us solve the question
Substitute x by 0 to find the value of y, if y = 0, then the line represents this equation passes through the origin point, then the equation shows a proportional relationship
∵ y = 50x + 2
∵ x = 0
∴ y = 50(0) + 2
∴ y = 2
→ That means the line that represents the equation does not pass through
the origin point
∴ The equation y = 50x + 2 is not proportional
∵ y = 20x
∵ x = 0
∴ y = 20(0)
∴ y = 0
→ That means the line that represents the equation passes through
the origin point
∴ The equation y = 20x is proportional
