FLASHCARD QUESTION
Front
What is the slope of a line that is perpendicular to the line represented by the equation y = mx + b?
Back
The slope of a line that is perpendicular to another line is the negative reciprocal of the slope of the original line. If the slope of the original line is m, the slope of the perpendicular line is -1/m.

FLASHCARD QUESTION
Front
How do you find the slope of a line given two points (x1, y1) and (x2, y2)?
Back
The slope (m) can be calculated using the formula m = (y2 - y1) / (x2 - x1).
