How do I know when a slope declines or ascends?

How to tell when a slope declines or ascends is to see if the line has a positive slope (i. e. m > 0), then y always increases when x increases and y always decreases when x decreases. Thus, the graph of the line starts at the botto left and goes towards the top right.

Answer: If the line is a positive slope, y increases when x increases too. So the line on the graph starts at the bottom left and goes towards the top right (than it's positive)
