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.
A proportional relationship can be represented by the equation ( y = kx ), where ( y ) and ( x ) are the variables, and ( k ) is the constant of proportionality. This equation indicates that as ( x ) changes, ( y ) changes in direct proportion to ( x ). The value of ( k ) determines the steepness of the line when the relationship is graphed, and it reflects the ratio of ( y ) to ( x ).
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 ).
You cannot represent a proportional relationship using an equation.

If you mean: y=7x -3 then it is a proportional relationship of a straight line equation.
The graph of a linear proportion will be a straight line passing through the origin. The equation will have the form y = mx, also written as y = kx.
In a proportional relationship, y is directly proportional to x, meaning y = kx, where k is the constant of proportionality. To find k, we can use the given values: 14 = k(8). Solving for k, we get k = 14/8 = 1.75. Therefore, the equation for y in terms of x is y = 1.75x.
Proportional is when it is proportional.
Directly proportional relationship is F=ma, F is directly proportional to a. Inversely proportional relationship is v=r/t, v is inversely proportional to t.
It is a straight line equation in the form of: y = mx+b whereas 'm' is the slope and 'b' is the y intercept
