Ex: Write the equation of the line which is parallel to y-axis and passing through the point P,
if
a) P(3,0) b) P(2,0)
Ex: Write the equations of the lines d and e.
5) Equation Of A Line Which Is Passing Through The Origin With Slope m:
Let line d be passing through the origin with slope m as
shown in the figure.
Then, line d is passing through the point (0,0) with slope m
.
Therefore, its equation is
y-y 1 = m.(x-x 1) → y-0=m.(x-0) → y=mx .
That is, the equation of the line passing through the origin with slope m is
y=mx
