Direct Proportion
Two variables whose ratio is constant have a linear relationship. The first variable is the second multiplied by the constant.
Derived unit
It is a direct proportion.
Direct Proportion
c, but the word is DIRECTLY, not dirctly!
If two variables are in direct relationship then the ratio of the two variables is known as the constant of proportion between them. In algebraic form, if X and Y are the two variables, then direct proportionality implies that Y = cX and c is the constant of proportionality.
It is the constant of proportionality.
It is the constant of proportionality.
Direct proportionality. Their graph would be a straight line through the origin, with the slope equal to the ratio.
Graphical: If two variables are proportional, the graph of one of the variables against the other is a straight line through the origin.Algebraic: If the ratio of the two variables is a constant.
The constant of proportionality between two variables is the ratio of one to the other.
