What is the slope of the line? Write your answer in decimal format

-1.25

Step-by-step explanation:

To find the slope you must use 2 points. For this graph, two points that work are (0,5) and (4,0). Then find the rise over run, which is the change in y over the change in x. Do this by using the slope formula, . Once plugged in this should simplify to -5/4. In decimal form, this equals -1.25.

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.
