Flashcard 21 - Math Flashcard Set for the SAT Exam

positive, \(0\)

A line that moves from the bottom left to the top right is an upward-sloping line. It has a positive slope. Recall that slope is defined as how much a line changes in the \(y\) direction with respect to its change in the \(x\) direction. A horizontal line doesn’t change in the \(y\) direction with respect to changes in the \(x\) direction, so its slope is \(0\).
