Did you know that if a line makes an angle of Ø with the xaxis
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 xaxis
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.
