I need help pls ill give brainliest if u help me.

Determine whether or not the equations represent a direct variation . Sort the equations into the appropiate category.

Direct variation (a has relation with b by a = kb, k is constant)

y = 3x

y = (2/7)x

-0.5x = y (or y = -0.5x)

Not direct variation (a has no relation with b by a = kb, k is constant)

x = -1

y = 2.2x + 7

y = 4

Hope this helps!

4 adults and 12 babies

step-by-step explanation:

4 x 7 = 28

12 x 15 = 180

180 + 28 =208

4 x 3 = 12

c. (3,2,6) is the answer.
