Slope from 2 Points

Front

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

Back

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

Front

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

Back

A positive slope indicates that as x increases, y also increases, showing an upward trend.

Front

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

Back

A negative slope indicates that as x increases, y decreases, showing a downward trend.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates a vertical line, where x does not change and y can take any value.

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates a horizontal line, where y remains constant as x changes.

Front

Find the slope of the line that passes through the points (2, 3) and (4, 7).

Back

2

Front

Find the slope of the line that passes through the points (1, 1) and (1, 5).

Back

undefined

Front

Find the slope of the line that passes through the points (3, 4) and (3, 4).

Back

0

Front

If the slope of a line is 3, what does this tell you about the change in y for a change in x?

Back

For every 1 unit increase in x, y increases by 3 units.
