Front

What is the formula to find the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

What does it mean if the slope is undefined?

Back

The slope is undefined when the line is vertical, meaning the x-coordinates of the two points are the same.

Front

How do you find the slope from the equation y - 3x = 1?

Back

Rearrange to slope-intercept form (y = mx + b): y = 3x + 1, so the slope is 3.
