A.
y = 2

B.
y = −2

C.
y = 2x

D.
y = −2x

Answer 1

i think it is A

Answer 2

when y = something*x
then substituting a particular x value should give you corresponding y value right?

Answer 3

in the graph, let's take x value 0, 1 , 2 for example,
by looking at the graph
in x= 0 case
y = 2
in x = 1 case
y = 2
in x = 2 case
y is still 2
so y is constant irrespective of x right?

Answer 4

yea

Answer 5

so y = 2 will be the answer :) and you are right :D

Answer 6

thanks!

Answer 7

shes cheating on k12 sophia

Answer 8

How?

Answer 9

now remember to substitute the values in standard equation y = something*x + some_constant

AND
any line parallel to x-axis is y = some constant
any line parallel to y-axis is x = some constant

Answer 10

thanks
