Answer: It has no slope.
Step-by-step explanation: The slope of a line on a graph represents the rate of change between the variables plotted on the x-axis and y-axis. In this case, the graph titled "Bianca's Height and Weight" has weight in pounds on the x-axis and height in inches on the y-axis.
Since the vertical line is at x = 130, it means that the weight is fixed at 130 pounds for all points on that line. Since the weight is constant and not changing, the line has no slope.
