Did you know that if a line makes an angle of Ø with the x-axis

then tanØ = slope of the line ?

so if tanØ = 2

Ø = 63.4°

if tanØ = -3

the line leans to the left and the line makes an acute angle of 71.6° with the x-axis

so a line with slope -3 is steeper.

The sign of the slope tells you which way the line leans.

if slope > 0, it leans to the right

if slope < 0 , it leans to the left

if slope = 0, the line is horizontal, has no lean.
