If we were to subsitute the points and graph the equation we would notice that the shape is the same for both: a 45 degree angle line that goes upleft and up right
the graph of y=|x| looks like a right angle corner that is facing up that is ballancing on the point (0,0)
the graph of y=|x|-4 is the same except that the graph is shifter 4 units to the right ie. the point ofo the graph/rightangle is on point (4,0)
You can't convert that into a mixed number. Unless you are talking about 4/5 + 4/5. The answer would be 1 3/5.
NO it is not well defined because well defined means not vague basically this is vague more details to why they are the ten and what are the ten. Hoped this helps
