FLASHCARD QUESTION
Front
What is a two-variable inequality?
Back
An inequality that involves two variables, typically written in the form of 'y < mx + b' or 'y ≥ mx + b', where m is the slope and b is the y-intercept.
2.
FLASHCARD QUESTION
Front
What does the solution set of a two-variable inequality represent?
Back
The set of all points (x, y) that satisfy the inequality, often represented graphically as a shaded region on a coordinate plane.
3.
FLASHCARD QUESTION
Front
How do you determine if a point is a solution to a two-variable inequality?
Back
Substitute the x and y values of the point into the inequality. If the inequality holds true, the point is part of the solution set.

FLASHCARD QUESTION
Front
What is the difference between '>' and '≥' in inequalities?
Back
'>' means that the value is strictly greater than, while '≥' means that the value is greater than or equal to.
5.
FLASHCARD QUESTION
Front
What does the graph of 'y < 2x - 3' look like?
Back
A dashed line representing the equation y = 2x - 3, with the area below the line shaded to indicate all points where y is less than 2x - 3.
6.
FLASHCARD QUESTION
Front
What is the significance of a dashed line in graphing inequalities?
Back
A dashed line indicates that points on the line are not included in the solution set (for '>' or '<' inequalities).

FLASHCARD QUESTION
Front
What does a solid line indicate in graphing inequalities?
Back
A solid line indicates that points on the line are included in the solution set (for '≥' or '≤' inequalities).
