Equation 2. [tex]y = 150x[/tex] represents a proportional relationship.
Here [tex]y=150x[/tex]
On rearranging we get, [tex]\frac{y}{x} =150[/tex]
Or, [tex]\frac{x}{y} =\frac{1}{150}[/tex]
Or, [tex]x:y=1:150[/tex]
from above expression we can say now equation 2 represents a proportional relationship and the other equations cannot show the proportional relationship.
Hence Equation 2. [tex]y = 150x[/tex] represents a proportional relationship.
