when graphing inequalities how do you know where the shading will be ?

OpenStudy (anonymous):

If the inequality is y > [equation], then shade the area above the graph, since all y values above the dashed line make the equation true. If the inequality is y < [equation], then shade the area below the graph, the all y values below the dashed line make the equation untrue

OpenStudy (anonymous):

combined inequalities. im sorry

OpenStudy (s3a):

y <= 2x+3 means y is less than or equal to that function so in other words, the shading is "under" the graph because "under" means smaller y values.

OpenStudy (s3a):

y >= 2x+3, the shading would be above it.

OpenStudy (anonymous):

Yes he's right

OpenStudy (s3a):

if i remember correctly

OpenStudy (anonymous):

i meant with combined inequalities... sorry

OpenStudy (s3a):

well you draw each line and then you have a polygon (aka a shape) and you shade the inside of the shape.

OpenStudy (s3a):

each line being each function representing each restriction

OpenStudy (anonymous):

graphing on a number line

OpenStudy (s3a):

what?

OpenStudy (anonymous):

example 5x - 4 > 6 or -4x + 5 > 1

OpenStudy (anonymous):

So how was your day breezy?

OpenStudy (anonymous):

it was good and fast how was urs ?

OpenStudy (anonymous):

Busy and stressful

OpenStudy (s3a):

a number line seems to be just for drawing the domain of a function (set of x values). if there's a way to draw inequalities on that, i don't know. sorry

OpenStudy (anonymous):

lol sounds like life to mee

OpenStudy (anonymous):

its ok thank you

OpenStudy (s3a):

you're welcome and sorry

OpenStudy (anonymous):

Life yes a stressfull one
