To verify the identity, you have that the left side of the equation becomes:
(1 + cosx)(1 - cosx) = (1 - cos^2 x)
because of the product of an expression by its conjugate result in a difference of squares. Or simplfy by expanding the factors and simplying.

Answer:
<em>y = - 2x + 5 </em>
Step-by-step explanation:
m , ( ,
)
y - = m( x -
)
~~~~~~~~~~~
m = - 2 and ( 4 , - 3 )
y - ( - 3 ) = - 2( x - 4 )
y + 3 = - 2x + 8
<em>y = - 2x + 5</em>
