Note:

1) If the slope > zero then the straight line makes an acute angle with the
???????????????? ?????????????????? ???? ?????? ?? – ????????????????????

2) If the slope < zero then the straight line makes an obtuse angle with the
positive direction to the x – coordinate

3) If the slope = zero then the straight line parallel to the x –axis
4) If the slope is undefined then the straight line parallel to the y –axis

Example:

Find the slope of the straight line that makes a positive angle in the positive
direction to x – axis , its measure

a) ?????? slope = tan 30 = ??
v??

b) ?????? slope = tan 45 = ??

c) ?????? slope = tan 60 = v??
