Answer:
y = 1/2 (2)x
      Step-by-step explanation:
Using the equation y = abx , substitute both of your given points into that equation.
2 = ab2 and 4 = ab3   Solve each equation for a.
 
2⁄b2    and 4⁄b3 = a     Therefore, 2⁄b2 = 4⁄b3
                               
Cross multiply: 2b3 = 4b2     Divide both sides by b2
 
2b = 4      a = 2/4 = 1/2
b = 2
