What is the slope intercept formula for a vertical line?

there isnt one i dont think. since the line never has a slope and rarely a y-intercept would be not way for an equation to be made unless it wa  y=mx+b but that just slop intercept form. I dont know if that righ but ig u can try it

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.
