Flashcards
Horizontal line
Horizontal line
A line with a slope of zero is a horizontal line. It runs parallel to the x-axis and has no vertical change.
Perpendicular lines
Perpendicular lines
Perpendicular lines have slopes that multiply to -1. This means one line's slope is the negative reciprocal of the other.
Boundary line inclusion
Boundary line inclusion
When the inequality is ≥ or ≤, the boundary line is included in the region. This means the points on the line are part of the solution.
