Answer:
the answer is (x,y) (1,2)
Let's plug the values and see which couple satisfy the equation: since 
, if we plug the values from the first option 
we have
which is correct.
If we plug the values from the second option 
we have
which is not correct
If we plug the values from the third option 
we have
which is not correct
If we plug the values from the fourth option 
we have
which is not correct
So, the answer is the first one.
Start by graphing y = |x|. Its vertex is at (0,0), and the graph opens up.
Now translate the entire graph 4 units up. The new vertex will be at (0,4). Draw an empty circle around this point.
Darken the graph of y = |x|+4 ONLY for the part which is left of the y-axis.
Now plot a dark dot at (0,4). Draw a dark, horiz. line from that dot to the right.
That's it!
