Multiple Select
4≤x≤10
Check all that are true regarding this compound inequality.
This is an "AND" type question
This is an "OR" type question
The graph will look like oars on a boat (kick out to the sides)
The graph will shade in between the values.
The values of 4 and 10 will have brackets on them.
5
Multiple Choice
What is the correct inequality notation for this graphed solution?
x<−3 or x>−2
x>−3 or x<−2
x≤−3 or x≥−2
x<−3 and x>−2
x>−3 and x<−2
6
Multiple Choice
What is the correct interval notation for this graphed solution?
(−3,2)
(−∞,−3)∪(−2,∞)
(−∞,−3]∪[−2,∞]
[−3,−2]

Multiple Choice
When trying to solve for y, which of the following should be the first step?
7y=8
4y=−3x+8
4y=3x+8
x+34y=38
10
Multiple Choice
What is the NEXT correct step in the following question when isolating for y:
5xy=9
5y=9−xy
y(x+5)=9

Fill in the Blanks
The slope of the given line is
Type answer...
y=−43x+7
14
Multiple Select
When graphing the given line, which of the following are TRUE?
Check ALL that apply!
y=−43x+7
Start by marking a point at (0,7)
Start by marking a point at (7,0)
To create a second point, move up 3 and right 4
To create a second point, move down 3 and right 4
You need to graph at least 2 points to make a line.
15
Multiple Choice
Which of the following is a VERTICAL line?
y=3x
x=3
y=3
x=3y
16
In this week, we will need to graph lines to solve systems, and sometimes the equation is not in slope-intercept form.

Multiple Choice
What is the slope of the given equation?
4x+3y=934

−34
−43
