More About Concept :-

• Direct Variation = If two quantities are linked in such a way that an increase in one quantity leads to a corresponding increase in the other and vice versa, then such a variation is called the direct variation. If two quantities are in direct variation, then we also say that they are proportional to each other.
• Inverse Variation = If two quantities are linked in such a way that an increase in one quantity causes a corresponding decrease in the other and vice versa, then such a variation is called an inverse variation. If two quantities are in inverse variation, then we also say that they are inversely proportional to each other.
