Question

Can someone please explain how I can figure out which of the following inequalities matches the graph because I am not understanding?
A.-6x+y<3
B.6x+y<3
C.6x-y<3
D.the correct inequality is not listed
Will medal and fan

Answer 1

first write the equation of the dotted line

Answer 2

I am not understanding this at all. What do you mean by the equation of the dotted line?

Answer 3

find the slope and y-intercept...

Answer 4

still there?

Answer 5

is y intercept 1/2

Answer 6

nope, please look at the graph again

Answer 7

im having a hard time when it is just a graph let me look again

Answer 8

is it 3

Answer 9

yeah, now find the slope

Answer 10

yippie the y intercept is alway where it crosses when x is 0 correct now the slope

Answer 11

not really sure would it be 1/3

Answer 12

use the slope formula if you are unsure

two points on the graph are (0,3) and (1,9)

Answer 13

6/1 =6

Answer 14

slope

Answer 15

@Vocaloid is the slope 6

Answer 16

yes

so the equation is y = 6x + 3

now on to the inequality part

Answer 17

since its shaded above the line, we conclude that the inequality must be

y > 6x + 3

we can rewrite this as

3 < y - 6x

Answer 18

so out of my answers this answer is not there

Answer 19

@Vocaloid am i right the answer is not listed. could we go back and could you tell me how you got your point (0,3) and (1,9) i have a test soon and would like to know how to get everything :)

Answer 20

yea it;s not listed

Answer 21

I just picked two points that were on the dotted line...

Answer 22

thanks
