Answer:
the period of the graph of 4cos(1/2x)-3 is twice as long as the period of 4cos(x)-3
B is your awnser! sorry if im wrong my calc shows its without a - symbol
Answer: is If something is a function, every x-value, only has one (1) y-value. If the line x = 0 intersects the graph in two points, there are to values for y (instead of one). Therefore the graph is not a function of x.

Answer:

The answer is the same line as given in the question.
Step-by-step explanation:
Hello!
Slope-intercept Form: 
- y = output
- m = slope
- x = input
- b = y-intercept
Given our Line: 
- slope =

- y-intercept =

Parallel lines have the same slope but a different y-intercept, so the second line should have a slope of
.
To find the y-intercept, we plug in the x and y values from the point into a blank equation with the slope and solve for b.
The equation is
, hence the same line.
