Answer:
B
Step-by-step explanation:
Looking at the graph, you can see that points E and D are on the same line. The coordinate for point E is [tex](4,-4)[/tex], and the coordinate for point D is [tex](4,2)[/tex]. Because they are on the same line, we only have to look at the y coordinates, [tex]-4[/tex] and [tex]2[/tex]. We add these together (ignoring the negative sign in [tex]4[/tex], because distance can't be negative) to get [tex]6[/tex], or B.
