The diameter and circumference of a circle.
The variation between two variable quantities with a constant ratio is called direct variation. In this relationship, as one variable increases or decreases, the other variable changes in proportion, maintaining the same ratio. Mathematically, this can be expressed as ( y = kx ), where ( k ) is a constant.
Direct variation.
The constant value of the ratio of two proportional quantities is known as the constant of proportionality. It represents the relationship between the two quantities, meaning that as one quantity changes, the other changes in a consistent manner. Mathematically, if ( y ) is proportional to ( x ), then this can be expressed as ( y = kx ), where ( k ) is the constant of proportionality. This constant remains the same regardless of the values of ( x ) and ( y ).
The relationship between two quantities with a constant rate of change or ratio is described as a linear relationship. In this case, the quantities can be expressed in the form of an equation, typically (y = mx + b), where (m) represents the constant rate of change (slope) and (b) is the y-intercept. If the ratio of the two quantities is constant, they are also said to be directly proportional, meaning that as one quantity increases or decreases, the other does so in a consistent manner.
In mathematics, two quantities are proportional if they vary in such a way that one of them is a constant multiple of the other.
Proportional
The answer is proportional.
Two quantities are said to be proportional if they vary in such a way that one of the quantities is a constant multiple of the other, or equivalently if they have a constant ratio.
The corresponding sides of similar solids have a constant ratio.
It is a direct proportion.
Two variables whose ratio is constant have a linear relationship. The first variable is the second multiplied by the constant.
