What does it mean when the x intercept in a slope is negative?
When the x-intercept of a line has a negative value, it indicates that the line crosses the x-axis to the left of the origin (0,0). This typically means that, at some point, the dependent variable (y) is zero for a negative value of the independent variable (x). In the context of a slope, a negative x-intercept can suggest that as the value of the independent variable decreases, the dependent variable changes in a way that leads to a negative relationship between the two.
