Frequently Asked Questions

Q.What is slope in math?

Slope measures the steepness of a line. m = rise/run = (y2-y1)/(x2-x1). Positive slope goes up left to right; negative slope goes down.

Q.What does undefined slope mean?

A vertical line has undefined slope because the run (x2-x1) = 0, causing division by zero. A horizontal line has zero slope.
