Comment on Slope

Does a line with negative slope have to pass by quadrant 1? I just drew a line imaginary that did not pass through quadrant 1 and only 2,3,4>

A line with a negative slope will always pass through quadrants 2 and 4, but the line need not pass through quadrant 1 (the line COULD pass through quadrant 1, but that is not guaranteed).

For example, the line y = -2x - 1 does not pass through quadrant 1.

Love the concept of rise/run to explain slope easy and elegant ! Thank you.
