We use the formula y = ax when we have a linear relationship between two variables, where 'a' represents the slope of the line. This formula is used to represent a straight line passing through the origin. On the other hand, we use the formula y = ax + c when we have a linear relationship between two variables but the line does not pass through the origin. Here, 'a' represents the slope of the line and 'c' represents the y-intercept, which is the point where the line intersects the y-axis. **
