Slope from Two Points

Front

If two points on a line have the same x-coordinate, the line must be:

Back

Vertical - Undefined slope

Front

What is the slope of a line that passes through the points (2, 4) and (6, 12)?

Back

2

Front

What kind of slope do downhill lines have?

Back

Negative

Front

What is the slope of a line that passes through the points (-3, -4) and (7, 6)?

Back

1

Front

What does a positive slope indicate about a line?

Back

The line goes uphill from left to right.

Front

What does a negative slope indicate about a line?

Back

The line goes downhill from left to right.

Front

What is the slope of a horizontal line?

Back

Zero slope

Front

What is the slope of a vertical line?

Back

Undefined slope

Front

How do you calculate the slope (m) between two points (x1, y1) and (x2, y2)?

Back

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

Front

If the slope is 1/7, what does this indicate about the line?

Back

The line is very shallow and slightly uphill.
