Direct variation math def
WebDirect Variation is said to be the relationship between two variables in which one is a constant multiple of the other. For example, when one variable changes the other, then they are said to be in proportion. If b is directly proportional to a the equation is of the form b = ka (where k is a constant). WebA direct variation is a linear equation that can be written in the form y = kx , where k is a nonzero constant. The number k is called the constant of proportionality or constant of variation. Graphically, we have a line that passes through the origin with the slope of k. Examples: y varies directly with x. y = 54 when x = 9.

WebSummary When we say that a variable varies directly as another variable, or is directly proportionate to another variable, we mean that the variable changes with the same ratio as the other variable increases. Also, if a variable decreases, then the other variable will decrease at the same rate. WebSummary:The type of variation can be identified by the graph of the relation. The graph of a direct variation is a straight line and starts at the The slope of the line is the constant of variation. direct variation is of the form y = mx, more commonly written as …
