Answer:
y=5/3x+7/3 
Step-by-step explanation:
Here are the points: (1,4) and (-2, -1)
let's first find the slope, which is with the equation m=(y2-y1)/(x2-x1) (m is the slope) 
 label the points: 
x1=1 
y1=4
x2=-2 
y2=-1 
now subsitute into the equation
m=(-1-4)/(-2-1)
m=-5/-3
m=5/3
the slope of the line 5/3 
Here's the equation so far: 
y=5/3x+b (b is a place holder) 
we can substitute either one of the points into the equation so far to find b, because the line will pass through both of them>
let's use (1,4) as an example
4=5/3(1)+b
4=5/3+b
subtract 5/3 from both sides
7/3=b
Now, put it all together: 
y=5/3x+7/3
Hope this helps! 
 
        
             
        
        
        
Plug n = 1 into the expression 20-9n and we get
20-9n = 20-9*1 = 20-9 = 11
So 11 is the first term of the series that we add up. Therefore the answer must be choice C, which has 11 listed as the first term added
        
             
        
        
        
Answer:
I am a bit confused on what the question is asking. But 64*186= 11904 and if we were to round that number it would be 12000. 21*98=2058 and that number rounded is 2100 or just 2000. (hope this is right and helps :D)

Z is greater than or equal to 7. 
you would put a 7 near the front of the number line and put a colored in circle above it. then you would draw a line from the circle to the other end of the line
