Question

Which relationship between x and y in the equation shows a proportional relationship

Answer 1

Answer:

The equation y = 3x shows a proportional relationship between x and y

Step-by-step 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
