The line that is the perpendicular bisector of the segment whose endpoints are r(-1,6) and (5,5)

First find midpoint:  \left( \frac{-1+5}{2}, \frac{6+5}{2}\right) = (2, 5.5)

Find slope of line that passes through R and S:    slope =  \frac{6-5}{-1-5} = \frac{-1}{6}  

Negative reciprocal of slope to get slope of perpendicular:    new slope = 6

Line will be:   y-5.5=6(x-2)

  y = 6x - 6.5

Step-by-step explanation:

answer: it's d

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32
