Finding Slope

Front

What is the formula to find the slope of a line?

Back

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

What does 'rise over run' mean in the context of slope?

Back

'Rise over run' refers to the vertical change (rise) divided by the horizontal change (run) between two points on a line.

Front

What does it mean if the slope of a line is undefined?

Back

An undefined slope indicates a vertical line where the x-coordinates are the same.

Front

If a line has a slope of 0, what does that indicate about the line?

Back

A slope of 0 indicates a horizontal line.

Front

How do you interpret a negative slope?

Back

A negative slope indicates that as the x-value increases, the y-value decreases.
