Suppose that the equation were y = 5 + x. Show in a graph like the one in Figure what the graph of that equation would look like. Is the relationship between x and y direct or inverse? Is the slope of the new equation greater or less than the slope shown in Figure? Now suppose that the equation were y = 5 – x. Show in a graph like the one in Figure what the graph of that equation would look like. Is the relationship between x and y direct or inverse? Is the slope of the new equation positive or negative? Would the slope of the equation y = 5 - x/2 be steeper or shallower than that of the one in y = 5 – x?
