WORKBOOK

Ex: Write the equation of the line passing through the origin with slope m, if
a) m=2 b) m=-2

Ex: In the given figure, n 1 is the first bisector line and n 2 is the second bisector line. Find the
equation of n 1 and n 2.

NOTE:

➢ In the equation y=mx+n , m is the slope (gradient) and n is the y-intercept of the line.
a
➢ The slope of a line ax+by+c=0 is m
b

Ex: Find the slopes of the following lines
i) y=3x-5 ii) y=-5x+3 iii) y=3x iv) y=-x

v) 3x+y=4 vi) 4x-y-5=0 vii)y=4 viii)x=7
Ex: If the slope of the line (m + 1)x – (2m – 1)y + 2m = 0 is 1 then find the x and y
intercepts. ( m R )
