Find the missing endpoint if s is the midpoint rt
s(-4,-6) and t (-7,-3) find r

 R = (-1, -9)

Step-by-step explanation:

Use the midpoint formula (sum of the endpoints divided by 2 equals the midpoint). Separate the x's and y's to solve more easily.

R(-1,-9)

Step-by-step explanation:

Given: S(-4,-6) and T(-7,-3)

Let coordinate of R(a,b)

Mid-point: This point is equi-distance from both end of line.

Mid-point formula:

   and    

Hence, The coordinate of R(-1,-9)

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
