Graph of a direct variation
WebSolution: Let us use the direct variation formula y = kx. Replace y with 72 and x with 8. k = 9. Therefore, the direct variation equation will be y = 9x. 2. When the values are y = 98 … WebDirect variation is represented as follows: Y = KX, where K is the constant of proportionality. The direct variation graph is a line through the origin. Inverse Variation. The quantities are said to be in inverse proportion if: …
