Question

How do i compare inequalities to the graph?

Answer 1

What do you mean?

Answer 2

do you have a graph?

Answer 3

like if u look at a graph and there's a in equality. How do you tell which inequality it is?

Answer 4

well they have to give you an equation

usuallay as y sign m*x+b

where sign can be >=, <=, < , >

if it is not in that form then solve for y :)
-----

>=, <=
if the sign is any of the above use a solid line

< , >
if the sign is any of the above then use a dotted or dashed line :)

Answer 5

do you know how to graph a normal y=mx+b equation?

Answer 6

yes i do

Answer 7

ooh then you have it made :D

basically now depending on

>=, <=, < , >

>=, shade above with solid line

<= shade below with solid line

< shade below with dashed line
> shade above with dashed line :)

Does that help?
