Front

What is the definition of a slope in a linear equation?

Back

The slope is the ratio of the rise (change in y) to the run (change in x) between two points on a line.

Front

What is the formula for the slope of a line given two points (x1, y1) and (x2, y2)?

Back

m = (y2 - y1) / (x2 - x1)

Front

What does it mean for a line to have an undefined slope?

Back

A line with an undefined slope is vertical and does not change in x as y changes.

Front

How do you find the y-intercept of a linear equation?

Back

Set x = 0 in the equation and solve for y.
