Finding slope from Two-Points

Front

What is the formula to find the slope 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 points (7,1) and (-2,1).

Back

The slope is 0.

Front

Calculate the slope of the points (1,2) and (3,4).

Back

The slope is 1.

Front

Calculate the slope of the points (3, 9) and (-2, 8).

Back

Front

Calculate the slope from the table of values: (x1, y1) = (1, 2), (x2, y2) = (3, 4).

Back

The slope is 1.

Front

Calculate the slope of the points (4,-4) and (2,0).

Back

The slope is -2.

Front

What is the slope of a line that rises 3 units for every 2 units it runs?

Back

Front

If the slope of a line is negative, what does that indicate about the direction of the line?

Back

A negative slope indicates that the line descends from left to right.
