3.1 Graph A match with number 2 because is less than -2 and when you count -10 to -2

graph B match with number 6 because 2 is greater than and not included and -2 is less than or equal and its include

Graph c mathch with number 3 because -2 is less than and its not included and 2 is less than or equal its include

GRAPH D match with number 1 because x is bigger than negaitve 2

graph E match with number 4 because x is greater than or equal 2 and less than equal negaitve 2

graph F match with number 5 because x is less than negative equal ess than equal 2

3.2

Explain what similar features are shown in the graph x>5 as you would graph it on a number line and x>5 as you would graph it on a coordinate plane. Also explain the similarities of x<=3 as graphed on a number line and x<=3 on a coordinate plane. Explain how this same thinking applies to y<2x+1 ?? How do you know which side of the line should be shaded since the line is slanted? Be sure to explain the short-cut method as well as the algebraic method you could use to prove that the correct side of the line has been s

1) the variable is by itself 2)its a solution and x is bigger than 5

1)variable by itself its a solution  less or equal than 3

you have to look at the sign less than you have to shade below than and it will be a dotted line

3.3 Y< = -4/9 X + 4

I MADE A TRIANGLE i calculate the slope and the y int its a solid line 3.4

Looking at the shaded graph in the document below, you need to identify a point that is a solution to the system and explain how you know it is a solution by looking at the graph. Also, identify a point that is a solution to only one of the inequalities, but NOT a solution to the system. Explain how you might test a point to determine whether it is a solution to the system or not? 5 nrgative 10 is a soution because its on the triangle 2) A PINT THAT IS A SOLUTION FROM ONE INEQUALITIES : -5 -4

3)a point that is a solution to only one of the inequalities, but NOT a solution to the system 0,4

4) you can test it by plugging 2 points one the graph in one inequalities
