Finding Slope from a Table, Graph, and Points

Front

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

Back

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

Front

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

Back

The line is horizontal.

Front

What does a positive slope indicate about the direction of a line?

Back

The line rises from left to right.

Front

What does a negative slope indicate about the direction of a line?

Back

The line falls from left to right.

Front

What is the slope of a vertical line?

Back

Undefined.

Front

How do you find the slope from a table of values?

Back

Calculate the change in y divided by the change in x between two points.
