WORKBOOK

Ex: Find the slope angle of the following lines.

0 90 o m tan 0, 90 o 180 o m tan 0,
Note: If
180 o tan tan , tan0 o 0 and tan90 o undefined

Ex: Find the slope angle and slope of each line given below.

NOTE: If the line d is passing through the points P(x 1, y 1) and Q(x 2 , y 2) then the slope of the
y y
line d will be m 2 1
d
x 2 x 1
