Why is slope of line l1 bigger than slope of l2?

C.Koushik · September 16, 2021, 10:18am

Since the slopes are negative. The magnitude (absolute value) of slope is still bigger for line l2, but since both slopes are negative, the slope of l1 is greater than the slope of l2

Greater angle means greater slope?

if the line is flat, the slope is zero
if the line is upright, the slope is not defined (±infinity)
if the line is raised towards the right, its slope increases from 0 to infinity as you make it steeper and steeper
if the line is raised towards the left, its slope decrease from 0 to negative infinity as you make it steeper and steeper
