Write an equation in direct variation form that contains the point (-8, -4). i need

y = 1/2 x.

Step-by-step explanation:

The graph of the equation will pass through the origin because it is direct variation, and its slope will be -4 /-8 =  1/2.

Therefore the equation is y = 1/2 x.

see explanation

Step-by-step explanation:

given that y varies directly as x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the point (- 8, - 4), that is x = - 8 and y = - 4

k = = = , hence

y = x ← equation of variation

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.
