Graphing
How many quadrants are on a coordinate grid?
4
The name of this symbol:
<
less than or equal to
How many answers can inequalities have?
Infinite!
What is |-3|?
3
Write the inequality for:
x is at least 6
x ≥ 6
What quadrant would (4, -2) be in?
Quadrant IV (or 4)
What symbols would make the graphed arrow go to the right?
Greater than and Greater than or equal to
What is the difference between equations and inequalities?
Equations only have 1 answer and involve = signs.
Inequalities have more than one answer and they have <, >, etc. signs.
place these integers in the right order from least to greatest
|-2|, |11|, -4, 0, -2
-4, -2, 0, |-2|, |11|
Write the inequality for:
x is no more than 17
x ≤ 17
What is located at (0, 8)?
y-axis (or right between Quadrants I and II)
How many symbols represent inequalities?
4
<, >, <, >
Solve:
x - 7 > 11
x > 18
Which is greater?
-4.2 or -4

Graph x > 2 on a number line
The graph will have an OPEN circle and a line going to the RIGHT!
On a coordinate grid, two negative coordinates would go in what quadrant?
Quadrant III (or 3)
What symbol would be represented by just a point on a number line?
=
Solve AND Graph:
5x < 35
x < 7
The graph should have an OPEN dot and line goes to the LEFT
What is the distance between (0,-4) and (2, -4)
2 spaces
Graph x ≤ -3 on a number line
The graph will have an CLOSED circle and a line going to the LEFT!
Two coordinates are neither positive or negative - where is the point located?
(0,0) - The origin!
When you hear the term "at most" which symbol does that represent?
≤
Solve AND Graph:
3/4 x ≥ 9
x ≥ 12
The graph should have a CLOSED dot and line goes to the RIGHT
Is the inequality true, if x = 2?
2x < 28
Yes it is!
4 < 28
Write the inequality for:
