看情况..数学上: y is directly proportional to x (x and y vary directly, or x and y are in direct variation)x和y成正比关系 统计学上:x and y are positively correlated or x and y have a positive correlation x和y是正相关的 一般用语 As x increases, y increases or x increa...
2. The ratio between y and x remains constant, indicating that y is directly proportional to x.3. So, when x grows larger, y gets bigger, and when x shrinks, y diminishes proportionally.
Ifyvaries directly asx, andy=15whenx=−5, findywhenx=7. Direct Variation: Direct variation explains a relationship between two variables that change in the same direction or are directly proportional. For such a relationship, the ratio of the two variables is equal to a constant,...
