We say Distance is directly proportional to time and thatâs why this represents a direct relation. A Directly Proportional Graph describes the relationship of a graph in words and mathematically. When the two measured physical quantities are plotted to form a straight line, we say they are âproportionalâ to each other.
Given two variables x and y, y is directly proportional to x (x and y vary directly, or x and y are in direct variation) if there is a non-zero constant k such that. The relation is often denoted, using the â symbol, as. and the constant ratio.
