Answer:
The equation y = 3x shows a proportional relationship between x and y
Explanation:
- The proportional relationship is represented graphically by a line passes through the origin point
- The equation of the proportional relationship is y = m x
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 = 3x
∵ x = 0
∴ y = 3(0)
∴ y = 0
→ That means the line that represents the equation passes through
the origin point
∴ The equation y = 3x shows a proportional relationship between x and y
