Graphing Inequalities

Utilizarás un círculo cerrado (sombreado) en la recta numérica para ≤ o ≥

Utilizarás un círculo abierto (sin sombrear) en la recta numérica para < o >

You will use a closed (shaded) circle on the number line for ≤ or ≥

You will use a open (unshaded) circle on the number line for < or >

Graphing Inequalities

Utilizarás una flecha -----> para representar gráficamente desigualdades que utilicen > o ≥

Utilizarás una flecha <----- para graficar desigualdades que utilicen < o ≤

You will use a -----> arrow to graph inequalities that use > or ≥

You will use a <----- arrow to graph inequalities that use < or ≤

Steps or questions to ask yourself

What is the comparing number?
Is it greater than or less than?
Is the comparing number included "equal to" (open or shaded)
What direction does the arrow go in?

Graphing

• Notice that the green line points to the right

• So any number larger than 2 is a solution

• Notice that there is a green shaded dot (Closed circle) on 2

• That means 2 is also a solution

• Possible solutions are 2 or any numbers larger than 2

• x > 2

Graphing

• Notice that the orange line points to the left

• So any number smaller than 3 is a solution

• Notice that there is a non shaded white dot (open circle) on 3

• That means 3 is not a solution

• Possible solutions are any numbers smaller than 3

• x < 3
