Y=1/3x - 6
Perpendicular means that the slope must be inverse. In your problem the slope is -3/1
So the inverse is 1/3
Answer: Option a.
Step-by-step explanation:
By definition, a functioon is even when:

And it is odd when:

Therefore, you can verify if the function is even substituting -x into the function:

Then:

It is an even function.
Answer:
x=2
Step-by-step explanation:
If 3x + y = 7, then y= 7 - 3x.
Substitute in x - 2y = 0
So:
x - 2(7-3x)=0
x-14+6x=0
7x=14
x=2
Anything that with a denominator that is a multiple of 4, for example:

,

,

,

, and so on.
Hope this helps you =)
