The equation is y = 3x.
Explanation:
Let the height of 2000 ml beaker = x
Given -
Height of 50 ml beaker, y = 1/3 of x
Equation to find the height of the 2000 ml beaker will be
y = 3x
which means the height of 2000 ml beaker is three times the height of 500 ml beaker.
Therefore, the equation is y = 3x.
