M(0,8) is the midpoint of segment rs. the coordinatws of s are (10,10). what are the coordinates of r?

The coordinates of R x= -10 , y=6

Step-by-step explanation:

The midpoint between two points (x1 , y1) and (x2 , y2) is

10 +x2 = 0

x2 = -10

10 + y2 =16

y2 = 16 -10 = 6

Point R is (-10 , 6)

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
