Final answer:
A negative intercept in mathematics refers to the point where a line or curve intersects the y-axis when the x-value is zero.
Step-by-step explanation:
A negative intercept in mathematics refers to the point where a line or curve intersects the y-axis when the x-value is zero. In other words, it represents the value of the dependent variable when the independent variable is zero. When the intercept is negative, it means that the y-value is below the x-axis at that point.
