Describe linear relationship

WebChapter 7: Looking for relationships: line graphs Figure 7.4 Graphs with curves (a) (b) When we talk of a variable changing ‘slowly’ or ‘rapidly’, we are using these terms in a relative sense to describe how the gradient (or slope) of a line changes. For a linear relationship, the gradient at any point along the line is the same. WebLinear Relationship. Siddharth Kalla 88.1K reads. A linear relationship is one where increasing or decreasing one variable n times will cause a corresponding increase or decrease of n times in the other variable too. In simpler words, if you double one variable, the other will double as well.
