since 14 is 2/3's of 21 the equation would be y=2/3x

The least common multiple is 150

First you need the midpoint formula. (x1+x2 divided by 2)and (y1+y2 divided by 2) Which would look like this.. 13+-6=7 and 7 divided by 2 is 3.5.... 8+-6=2 And 2 divided by 2 is 1. so your answer is (3.5, 1)

**Step-by-step explanation:**

M(8.-2), M'(x,y) , =(-5,1)

--> x - 8 = -5 --> x= 3

---> y+2 = 1 --> y =-1

so M'(3,-1) and its reflection y-axis is (-3,-1)

It equals 197 feet

hope this helps:)
