Answer:
2
Step-by-step explanation:
we know the line goes through the origin, so we have point (0,0). next, find another point the line goes through. for example, point (2,4)
the slope formula for points (x1, y1) and (x2, y2) is (y2 - y1) / (x2 - x1). plug in the 2 points to get (4-0)/(2-0) = 4/2 = 2
 
        
             
        
        
        
The answer is A. 
You can get this by modeling the function. It's slope and y intercept will yield the equation y = -.5x +1.5. Then you can try the ordered pairs in that, all of which work.
        
             
        
        
        
Answer:Is an estimate of the average grams of salt used in 2012
Step-by-step explanation: Let
x ---> the number of years since 2012
f(x) ---> is the total amount of salt ingested in grams
we have
This is a linear equation in slope intercept form
where
The slope is equal to
The y-intercept or initial value is equal to
The y-intercept is the value of the function f(x) when the value of x is equal to zero
In this context, the y-intercept is the average amount of grams of salt ingested  in the year 2012
The exact value of the average amount of grams of salt ingested  in the year 2012 is 3,554 grams (see the data in the table)
Compare the exact value with the y-intercept
therefore
3,548 grams Is an estimate of the average grams of salt used in 2012
 
        
             
        
        
        
Answer:
 a= (1,4)
b=(4,2)
c=(2,6)
d=(2,-1)
Step-by-step explanation:
All I did was looked at the regions the points began and ended. I'm not 100% this is correct but I hope I helped!
