Answer:
Domain: 1, 2, 3, 4
Range: 1, 2, 3, 4
Step-by-step explanation:
The domain is the first coordinate in an ordered pair which is x. In this set of ordered pairs, the first coordinates ( x ) are 1, 2, 3, 4. The range is the second coordinate in an ordered pair which is y. The range of this set of ordered pairs is 1, 2, 3, 4.

Answer:
line C
Step-by-step explanation:
The equation would be
y= 1/2x
So that means the slope is 1/2
Starting at (0,0) we would go up 1 and over 2
That would be point (1,2)
That is the purple line, line C
No. A cube is a 3D figure and polygon is a 2D one.
