Answer:
length between is <u>8</u><u>.</u><u>5</u><u>4</u><u> </u><u>units</u>
Step-by-step explanation:
Formular:

x1 is -4
x2 is 4
y1 is 4
y2 is 1

Measure which ever side of the triangle and that’ll be the length of pq
It's the first one. y can equal x as long as y doesn't equal x multiple times. We also know the last two are wrong because they're saying the same thing. A linear function is a straight line.
Checking answer A:
distance from U to V = -2-(-11)=9
distance from U to W =7-(-2)=9 -> same distance !
checking answer B:
distance U-V : -2-(-8)=6
U-W : -2-(-6)=4 -> not the same distance
answer C :
U-V : -2-(-6)=4
U-W : 6-(-2)=8 -> not the same distance
answer D :
U-V : 0-(-2)=2
U-W : 2-(-2)=4 -> not the same distance
Conclusion : answer A
