Umm the issue is that there are 2 y-values for one x-value
Can you spot that?
Hint: Each paired coordinate has the form (x-value, y-value)

Ok If you noticed you have 4  paired coordinates or rather 4 pairs and each pair has 2 numbers. The first one represents an x value and the second one represents a y-value on the x-y coordinate grid. 
So lets graph all the points so we can get a lil more concrete
