Can Some One Pls Teach Me How To Graph An Inequality Because I Want To Know How Here Are Some Examples class=

Sagot :

Answer:

Sure!

Step-by-step explanation:

So first of all, see whether the symbol is ≤ or <

≤ means a filled circle while < means open.

(please note it is the same for ≥ and >)

Place the circle on the number that is given

for example, the first one is x<-3, so you will place an open circle on -3

You will use rays when doing inequalities. A ray starts at one point and goes infinitely on to either the left or right.

The point (NOT THE OPEN SIDE) of the < ≤ or >≥ symbol is the direction the ray goes.

So the first one, you would place an open circle on -3, with the ray going on the left.

(if this is helped you, please give brainliest, trying to get an achievement)

Step-by-step explanation:

Remember, you must mark the point  (the number) with either an outlined circle or a filled circle...

When graphing a linear inequality on a number line, use an open circle for "less than" or "greater than", and a closed circle for "less than or equal to" or "greater than or equal to".

edit...sorry my arrow definitions are different and probably confusing haha...

what i mean is draw a long ray depending on the sign of the number...

to further elaborate, draw the ray left for a less than inequality and right for a greater than inequality.

Less than = <

greater than = >

"less than or equal to" = ≤

"greater than or equal to" ≥

#1

x < -3

step 1, mark the point on -3 with a open circle.

step 2, draw a line going left with a arrow at the end...

#2

x ≥ -5

step 1, mark the point on -5 with a closed circle

step 2, draw a line going right.

#3

x ≤ -2

step 1, mark the point at -2 with a closed circle

step 2, deaw a long arrow going left

#4

x > 7

mark a point at 7, with open circle

draw a line going right...
