When a line slopes upwards moving to the right, the variable measured on the x-axis and the variable measured on the y-axis are directly related. This means that as the value of the x-axis variable increases, the value of the y-axis variable also increases. Option A is incorrect because if two variables are directly related, a graph of the two variables has a positive slope. Option B is incorrect because when a line slopes downwards moving to the right, the variable measured on the x-axis and the variable measured on the y-axis are inversely related. Option D is incorrect because the statement indicates a direct relationship between temperature and ice cream consumption, not an inverse relationship.
