slope two points

Front

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

Back

The slope (m) is calculated using the formula: m = (y2 - y1) / (x2 - x1).

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical.

Front

Calculate the slope of the line that passes through the points (1, 2) and (4, 5).

Back

The slope is m = (5 - 2) / (4 - 1) = 3/3 = 1.

Front

If a line passes through the points (2, 3) and (2, 7), what is the slope?

Back

The slope is undefined because the x-coordinates are the same.

Front

What is the slope of a line that is increasing?

Back

The slope of an increasing line is positive.

Front

What is the slope of a line that is decreasing?

Back

The slope of a decreasing line is negative.

Front

Find the slope of the line that passes through the points (5, 1) and (5, -3).

Back

The slope is undefined.

Front

Calculate the slope between the points (3, 4) and (-1, 4).

Back

The slope is m = (4 - 4) / (-1 - 3) = 0.

Front

What is the slope of the line that passes through (0, 0) and (4, 4)?

Back

The slope is m = (4 - 0) / (4 - 0) = 1.
