Z =(17 + 4w)/(w - m) I believe
.25
You just move the decimal forward 2 spaces
The first one is the answer because
|6-5|<3 and 1<3
|4-5|<3 and -1<3
|2-5|<3 and -3<3
|0-5|<3 and -5<3
|-2-5|<3 and -7<3
|-4-5|<3 and -9<3
|-6-5|<3 and -11<3
Their corresponding sides are proportional and their corresponding angles are equal.
