Front

What is the slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you calculate the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

What does the slope of a line indicate?

Back

The steepness and direction of the line.

Front

If a line has a slope of 0, what does that mean?

Back

The line is horizontal.

Front

If a line has an undefined slope, what does that mean?

Back

The line is vertical.
