Answer:
If the slope of a line is negative, it means that the line is sloping downward from left to right. In other words, as the value of x increases, the value of y decreases. This is in contrast to a positive slope, where as the value of x increases, the value of y also increases. So, if the slope of the line y = x is changed to a negative value, the line will still have the same general shape, but it will be flipped upside-down and will slope downward from left to right
