Find the y-intercept of the line, show all your work: -4x - 2y = 16

the y intercept is -8

Step-by-step explanation:

y = mx+b

where m is the slope and b is the y intercept

-4x-2y = 16

we need to get y alone

add 4x to each side

-4x+4x-2y = 4x+16

-2y = 4x+16

divide each side by -2

-2y/2 = 4x/-2 + 16/-2

y = -2x -8

the slope is -2

the y intercept is -8

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.
