Answer:
a. or 
Step-by-step explanation:
Slope is equal to y1-y2 over x1-x2.
So the equation would be:

2-(-1)=2+1=3
-3-(-1)=-3+1=-2
So the answer is:

Answer (quite straightforward):
650
= 65 x 10
Remember that a parallel line has the same slope...
So we already know the slope of the line containing point C is -4.
Using point slope equation, we can do...
y-y₁=m(x-x₁)
y-7= -4(x-4)
y-7- -4x+16
*Add seven to both sides...* y=-4x+23
There is you answer... hope this helps!
Answer:

Period is 2π
Horizontal shift = 0
Step-by-step explanation:
We know that
and as
, so, we can write
Therefore, the if
then
(Answer)
Now, the period of
is 2π, hence the period of
is also 2π. (Answer)
Again.
, hence, the horizontal shift of
is 0. (Answer)
