Answer:
I love math anyways
The ans is in the picture with the steps how i got it 
(hope it helps i plz have brainlist :D hehe)
step-by-step explanation:
 
        
             
        
        
        
The slope of the line is 2/1 and the y-intercept is (0,-3). Using that information, we can figure out two points on the line.
Point 1: (0,-3)
Point 2: (1,-1)
 
        
             
        
        
        
Answer:
 is an even function.
 is an even function. 
Step-by-step explanation:
Recall when it means when a function is even or odd. An even function has the following property: 

And an odd function has the following property: 

So, let's test some values for cos(x). 
Let's use π/3: 

From the unit circle, was can see that this is 1/2 (refer to the x-coordinate). 
Now, let's find -π/3. This is the same as 5π/3. Thus: 

And again from the unit circle, we can see that this is 1/2. 
Therefore, despite the negative, the function outputs the same value. 
Cosine is an even function. 
Notes: 
Cosine is an even function and sine is an odd function. It's helpful to remember these as they can help you solve some trig problems!
