Determine the x- and y-intercepts of the graph of y=-1/2x-4. then plot the intercepts to graph the equation.

for x, put a point on 0,8

for y, put a point on -2,0

it should look like this

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.
