Answer: A
Step-by-step explanation:
r = j + 3
We subtitube r to find j,
r = 9 j = 9 + 3 = 12
r = 15 j = 15 + 3 =18
r = 21 j = 21 + 3 = 24
And we found A as answes.
The length of AA' is the squareroot of 29.
The Answer is the first one because not only do you need a -9 and+3 the positive 3 is the y intercept so it should be at the end and the -9 is the x intercept so it would be in the front
Hope this helps you:)
Answer:

= 162000 m ( convert m to km by dividing with 1000)
= 162 km
