Point m is the midpoint of kl. m(1,-1) and l(8,-7. what are the coordinates of point k?

(-6, 5)

Step-by-step explanation:

Use the Midpoint Formula:

Separate the x's and y's and solve them individually:

            So, the k-coordinate is (-6, 5)

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

answer: the answer is e
