It is an expression, not an equation and so cannot be proportional nor non-proportional.
To find an unknown value in a proportional relationship, you can set up a ratio equation based on the known values. For example, if you have a proportional relationship expressed as ( \frac{a}{b} = \frac{c}{d} ), where ( a ) and ( b ) are known values, and ( c ) is the unknown, you can cross-multiply to solve for ( c ) by rearranging the equation to ( c = \frac{a \cdot d}{b} ). This allows you to calculate the unknown value while maintaining the proportional relationship.

If each side of the equation is a fraction, then it is a proportion.
To write an equation representing a proportional relationship, you start with the general form ( y = kx ), where ( k ) is the constant of proportionality. This equation indicates that ( y ) varies directly with ( x ); as ( x ) increases or decreases, ( y ) does so by the same factor determined by ( k ). To find ( k ), you can use known values of ( x ) and ( y ) from the relationship.

To determine if a relationship is proportional by examining an equation, check if it can be expressed in the form (y = kx), where (k) is a constant. This indicates that (y) varies directly with (x) and passes through the origin (0,0). If the equation includes an additional constant term or a different form, it signifies that the relationship is not proportional.
Answer: ProportionalorDirectly Proportional
If it passes through the origin
The equation ( y = 13x ) does represent a proportional relationship between ( x ) and ( y ). In this equation, ( y ) is directly proportional to ( x ) with a constant of proportionality equal to 13. This means that if ( x ) increases or decreases, ( y ) will change by the same factor, maintaining a constant ratio of ( \frac{y}{x} = 13 ).
