How to find the intersection of line y=12x+8 with axis?

We know that when a line is intersecting x axis, the value
of x is the solution of the equation.


We'll have the
equation of the line y = 12x+8 (1).


12x+8 = 0
(2)


x = -8/12


x =
-2/3


Comparing (1) and (2), we'll get y =
0.


So, the line is intercepting x axis in the point (-2/3 ,
0).


We'll conclude that if we want to find out the y
intercepting point, we'll have to put x = 0.


y =
12x+8


For x = 0 => y = 12*0 +
8


y =
8


Therefore, the line is intercepting x axis
in the point (-2/3 , 0) and the line is intercepting y axis in the point (0 ,
8).

Can (sec x - cosec x) / (tan x - cot x) be simplified further?

Given the expression ( sec x - csec x ) / (tan x - cot x) We need to simplify. We will use trigonometric identities ...
