You can either use the usual formula for the equation of a line when given two points 
Or we can make some more precise reasoning, specific to this case: the y intercept is 3. When a line is written as 
, the coefficient q is the y intercept. So, the second and third options are surely wrong.
Moreover, the slope m is the ratio between the difference bewteen the y coordinates and the x coordinates of two points on the line.
In our case, the two points differ by -1 units vertically, and 3 units horizontally. This implies that the slope is -1/3.
So, we have
Answer:
n = -14
Step-by-step explanation:
-3(n+9)=15
Distribute -3 to (n+9):
-3n - 27 = 15
Add 27 to both sides:
-3n = 42
Divide both sides by -3:
n = -14
Functions cannot have the same X value (the first number), but they can have the same Y value (the second number).
<span>A. {(1,2),(2,3),(3,4),(2,1),(1,0)}
B. {(2,−8),(6,4),(−3,9),(2,0),(−5,3)}
C. {(1,−3),(1,−1),(1,1),(1,3),(1,5)}
D. {(−2,5),(7,5),(−4,0),(3,1),(0,−6)}
Choice A. has two repeating X values [(1,2) and (1,0), (2,3) and (2,1)]
Choice B. has one repeating X value [(2, -8) and (2,0)]
Choice C. all has a repeating X value (1)
Choice D doesn't have any repeating X values.
In short, your answer would be choice D [</span><span>{(−2,5),(7,5),(−4,0),(3,1),(0,−6)}] because it does not have any repeating X values.</span>
Your answer is 5.499.
Hope you do well on whatever it is, and glad I could help :)
