Consider the following equations: −x − y = 1

y = x + 3

If the two equations are graphed, at what point do the lines representing the two equations intersect?

a

(−1, 2)

b

(−2, 1)

c

(1, −2)

d

(2, −1)

The Answer is: (-2,1)

Step-by-step explanation:

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
