How can you if a relationship is proportional by looking at an equation?
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.
How do you write an equation for a proportional relationship?
To write an equation for a proportional relationship, identify the two variables involved, typically denoted as (y) and (x). The equation can be expressed in the form (y = kx), where (k) is the constant of proportionality that represents the ratio between (y) and (x). Ensure that (k) is determined by using known values of (y) and (x) from the relationship.
How can you use an equation to find an unknown value in a proportional relationship?
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.
How do you represent a proportional relationship using an equation?
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 ).

How can you represent a proportional relationship using an equation?
You cannot represent a proportional relationship using an equation.
Are time and power directly or inversly proportional?
Time and power are inversely proportional to each other. This means that if power increases, time decreases, and vice versa. This relationship is expressed by the equation P = W/t, where P represents power, W represents work, and t represents time.

State Boyle's law in words and as an equation?
Boyle's Law states that the pressure of a gas is inversely proportional to its volume, when the temperature is held constant. Mathematically, this relationship is expressed as P1V1 = P2V2, where P represents pressure and V represents volume.

Does the equation y13x show a proportional relationship between x and y?
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 ).
