Answer 5

You're looking for an equation that has constant change so it's not lik 3,5,9,13 but like 2,4,6,8 (multiplying by 2)

Answer 6

The linear variation equation has to be in the form: y = k*x where k is the variation constant. Which option looks to be in that form?

Answer 7

Where you have y=xk

Answer 8

d

Answer 9

Not quite if you plugged in 1,2,3 for x you would get 1,4,9 so that's not constant change

Answer 10

y = x^2 is a quadratic and is not a line. Its graph is a parabola.

Answer 11

^^^^^that too

Answer 12

Answer 13

Is it C?

Answer 14

Look at the options.

Where do you see y = a number multiplied by x?

Answer 15

Which equation follows the pattern y=xk

Answer 16

>>Is it C?

Answer 17

Lol we're thinking the same thing at @Directrix

Answer 18

Yes. y = 1/2 x

Answer 19

So it's B.

Answer 20

No

Answer 21

That 1 divided by a number we need some number times a number

Answer 22

One over x is not the same as x.

Answer 23

You already chose the correct answer. @Gokuporter
