Welcome to QuestionCove! Please make sure to attach the image if it comes with your question. Given the description I assume that the graph looks something like this |dw:1729457850127:dw| If that is right, that means the line is laying horizontally. Remember there are unique slopes for horizontal and vertical lines: * Horizontal lines have a slope of zero since y is neither increasing or decreasing. * Vertical lines have an undefined slope since y is equal to multiple numbers at the same x value.
