Finding Slope

Front

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

Back

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

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line falls from left to right.

If a line has a slope of -1, what does this mean about the line's direction?

Back

The line falls at a 45-degree angle from left to right.
