Answer: C. 
=======================================================
Explanation:
The x intercept always occurs when y = 0.
Use the unit circle to determine that
when 
So if
, then we have

which shows us that
is the location of one of the infinitely many x intercepts for this function.
Answer:
y = -2x + 6
Step-by-step explanation:
Since we already have the slope we just need to find the y-intercept.
To do that just plug in the point you were given. (1,4)
4 = -2(1) + b (b represents the y-intercept)
4 = -2 + b (add 2 on both sides)
6 = b
y = -2x + 6 is the equation
Hope this helps!!
Answer:
I think it might be C. I am not sure.
X=numerator
fraction=x/16
x / 16=3/4
x=16(3/4)
x=(16*3)/4
x=12
fraction=12/16
To check:
12/16=0.75
3/4=0.75
X to the second power=9x^2=9
