Answer: Milimeters (mm)
Step-by-step explanation:
The magnitude of YZ is 8.6
<u>Explanation:</u>
<u />
Y( -4, 12)
Z ( 1, 19)
Magnitude of YZ = ?
We know:

On substituting the value we get:

Thus, the magnitude of YZ is 8.6
I think this is right if not oh well but the domain of marcos mapping diagram is paired with exactly one element in the range.
Slope = change in Y / change in x
Slope = (-2 - -2) / (-9 - -1)
Simplify:
Slope = 0/-8 = 0
Slope = 0
