Or inequalities. greater than, > , and less than, < , mean the solution does not contain the number. so would you use and open circle or a closed circle to graph on a number line for inequalities. greater than or equal to, > , and less than or equal to, < , mean the solution does contain the number. so would you use and open circle or a closed circle to graph on a number

In case of inequalities we have following two rules.

Rule 1:

If we have just greater than > or less than < sign , then we would use open cirlce.

An open dot means the function has no definition at the specific point

Greater Than, >, and Less Than, <, mean the solution does NOT contain the number

Rule 2:

For inequalities. Greater Than or Equal TO, >, and Less Than or Equal TO, <, mean the solution does contain the number.

So in that case we will use closed circle.

Hope that helps.

Closed circle for the first one

Open circle for the second one

step-by-step explanation:

2/3

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves
