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

Find the slope of the points (1, 8) and (3, 12).

Back

2

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as x increases, y also increases.

Front

What does a negative slope indicate about a line?

Back

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

Front

What is the slope of a horizontal line?

Back

0

Front

What is the slope of a vertical line?

Back

Undefined

Front

If the slope of a line is 3, what does this mean in terms of rise over run?

Back

For every 3 units the line rises, it runs 1 unit to the right.

Front

Find the slope of the points (12, -2) and (4, -6).

Back

1/2

Front

What type of slope does the line with points (2, 3) and (4, 1) have?

Back

Negative slope

Front

If a line has a slope of 0, what can be said about the y-values?

Back

The y-values remain constant regardless of x.
