Symbols
What way do you shade when the arrow is >
Up
What is the first step when graphing an inequality?
Graphing the line
What is a system of inequalities?
Two or more inequalities graphed together.
What is a coordinate pair?
A point written as (x,y).
Shade above or below for y<4?
Below.
What symbol is this? <
Less than
What does the line represent?
The line represents the equation on a graph
What is the solution to a system of inequalities?
The overlapping shaded region.
What is slope?
Rise over run
Shade above or below for y≥−2x+3?
Above.
What is a inequality
a statement that compares two values or expressions, showing that they are not equal, or that one is greater than or less than another
Which axis goes left and right on a graph?
The x-axis.
What happens if there is no overlapping shaded region?
The system has no solution.
What is the y-intercept?
Where the line crosses the y-axis.
Solid or dashed line for y≤5x−1?
Solid line
When do you use dashed and solid lines
If the symbol has a line under it then you use a solid line but if it has no line under it then it is dashed
What happens to the graph when the inequality symbol is≥ or ≤?
You use a solid line.
What do you do after graphing both inequalities?
Find where the shading overlaps.
What does the double shaded region mean?
Any point within this area satisfies every inequality in the system simultaneously
Solid or dashed line for 2y>x+2?
Dashed line.
What type of line is less than or equal to and what way to shade?
dashed line shade down.
What does shading represent on an inequality graph?
All the solutions that make the inequality true.
What do you call the area where two inequalities overlap?
What is a boundary line?
The line separating true and false solutions.
What is the solution area called when two shaded regions overlap?
The intersection (or overlapping region).
