Find the slope of the line through each pair of points (12, -18), (11, 12)

-30

Step-by-step explanation:

The slope of a line given two points can be found by

m = (y2-y1)/(x2-x1)

    = (12- -18)/(11-12)

    = (12+18)/(-1)

     =30/-1

     = -30

c. prove the lengths are the same.

step-by-step explanation:

you need to prove the segments are congruent. congruent segments have the same length. find the lengths of the segments using the distance formula, and compare them.

answer: c. prove the lengths are the same.

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35
