What happens to a graph of a line if the slope changes from 2 to -2?

When the slope of a line changes from 2 to -2, the line rotates around its y-intercept. A slope of 2 indicates a steep upward incline, while a slope of -2 indicates a steep downward incline. As a result, the line will flip direction, moving from rising to falling as it crosses the y-axis. The y-intercept remains the same, but the overall orientation of the line changes significantly.
