Answer:

The equation y = 20x is proportional ⇒ B

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 = 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
