100
When graphing equations do you shade?
No
100
When graphing an inequality with the > sign will the line be dotted or unbroken?
Dotted
200
What does the Standard Form for a line look like?
y=mx+b
200
When graphing equations do you use dotted lines, unbroken lines, or both?
Unbroken Lines
200
When graphing an inequality with the < sign where do you shade?
The side with lesser numbers (negative)
300
When graphing equations and inequalities, what is the first point you plot?
The y-intercept
300
Do equations use = or < >
=
300
Graph y< 2x+ 3
(0,3) (1,1) shade the side with lesser numbers

What are at three differences between graphing inequalities and graphing equations?
*You shade graphed inequalities *Graphed inequalities can have dotted or unbroken lines *Inequalities have the less than, more than, less than or equal to, and more than or equal to signs *Equations have the equals sign
