Answer:
Graph 1: u-v
Graph 2: u-w
Graph 3: w-v
Graph 4: v-u
Step-by-step explanation:
First, let us find u-v, u-w, w-v, v-u.
<u>u-v:</u>
<-2,-7> - <3,-4> = <-2-3,-7-(-4)>= <-5,-3>
<u>u-w:</u>
<-2,-7> - <5,1> = <-2-5,-7-1> = <-7,-8>
<u>w-v:</u>
<5,1> - <3,-4> = <5-3,1-(-4)> = <2,5>
<u>v-u:</u>
<3,-4> - <-2,-7> = <3-(-2),-4-(-7)> = <5,3>
Then we can match the results with the graphs.
Graph 1: u-v
Graph 2: u-w
Graph 3: w-v
Graph 4: v-u
