Suppose that y …
Web13 jun. 2014 · There are two types of variation used in math. Direct variation means (Y varies directly with x) y = kx. Indirect variation means (Y varies indirectly with x ) y = k/x. So, if the question says - y varies indirectly with x, and for a value of x=3, y=4, then this is the problem to solve. y = k/x. 4 = k/3. WebAnd this essentially comes from the fact that because y Berries directly with X, we know that why over X is equal to some constant K. So that means that if we plug in one number one set of points x y, this should be equal to another set of points x y that lie within the same direct variation.
Web11 dec. 2024 · If x varies directly with y, we have a linear equation and can assume it has the form y = mx + b. As x changes up or down, y will follow, at a rate determined by m, the slope. b is the y-intercept, or where the line crosses the y axis at x = 0.
