For every x value, there should be only one y value. Or, for every input there is only one output.
A - Incorrect - there are two 2's for the x values and each of them has a different y value
B - Correct - all of the x values are different and all of the y values are different
C - Incorrect - there are two 11's for the x values and each of them has a different y value
D - Incorrect - there are two 3's for the x values and each of them has a different y value
Hope this helps! :)

Answer:
n = -2
Step-by-step explanation:
4n + 12 = 4
Subtract 12 from both sides.
4n = -8
Divide both sides by 4.
n = -2
The y intercept is seven so you would start by placing a point on (0,7). Then you count Down four points because the slope is a negative number and then count nine points to the right. You would have to keep counting down four points and the right nine points until your line was long enough.
2x + x = 24
so x = 24/3 = 8 ft. (smaller length)
2x = 16 ft. (larger length)
