Question

Do I shade above or below on these inequalities ?

1. y > 4/7 + 4 ((Point: 4,7))

2. y > -7/3 - 7 ((Point: -7,3))

Answer 1

is there a x component?

Answer 2

What do you mean?

Answer 3

How am I suppose to know when it's a dotted line or a straight line?
and how Do I know when i'm suppose to shade up or down

Answer 4

Well there's probably an x missing in your inequalities. It should be sth like :
y > 4/7 x +4

Answer 5

dotted means its only greater or smaller, the straight line means its greater than or equal to, OR smaller than or equal to.

Answer 6

its dotted when there is not a line under the sign

Answer 7

I don't have an X

Answer 8

If there's no X it should be sth like that

Answer 9

How would I write an equation for the inequlaties? like to solve it

Answer 10

You write y = 4/7 + 4

Answer 11

if its less then, you shade below the line and if it is greater then, you shade above the line

Answer 12

use a dotted line if there is no equal sign
use a solid line if there is an equal sign

Answer 13

Yeah, but I need a full problem.

like, this

-3y - 8x <9
+8 +8
--------------
-3y < 8x + 9
--- ------
-3 -3

y> -8/3 - 1

idk, how to get the other inequalities in a problem like that.

Answer 14

-3y - 8x < 9 (add 8x to both sides)
-3y < 8x + 9 (divide both sides by -3)
y < -8/3x - 3

Answer 15

oops...I forgot to change the sign
y > -8/3x - 3
shading would be above the line because it is greater then

Answer 16

I need the other problems up there ^^^^^^^^
not the one I just did

Answer 17

there should be x's in those problems....is there ?

Answer 18

no.... idk how to get the x's

Answer 19

that other problem (^^) doesn't have an x

Answer 20

are those the original problems ? Did you do anything to them or is that exactly how they are written ?

Answer 21

That's just what I got off of the graph I made.
like, It was a triangle in a graph and the one problem that I just did was one I made up then got the one point. but the other 2 are the other points in the triangle.
I got the problem by doing that whole up and over thing.

Answer 22

y < 4/7 + 4
y < 4/7 + 28/4
y < 32/4
y < 8
????
sorry...I do not know :(

Answer 23

oops...> greater then
if it is greater then, shading goes above the line
