Equation of a line through a givin point (a,b) and having slope m i.e. tan∂ = m is given by :
y-b = m(x-a) .......... (1)
In the given problem we have the values as :
m = 6
a = 0
b = 9
substituting in (1) above, we get
y-9 = 6(x-0)
or
y-9 = 6x
or
6x-y+9 = 0 ........... (2)
This is the required equation to the line.
Here the only trick was to remember the equation which represents a straight line passing through a given point & having a certain slope.
