Slope With Two 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

Find the slope of the line that passes through the points (1, -19) and (-2, -7).

Back

m = -4

Front

Find the slope of the line that passes through the points (2, 4) and (6, 12).

Back

m = 2

Front

Determine the slope of the line that passes through the points (3, 2) and (6, 5).

Back

m = 1

Front

Find the slope of the line that passes through the points (-3, -4) and (7, 6).

Back

m = 1

Front

Find the slope of the line that passes through the points (10, 1) and (5, 2).

Back

m = -1/5

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line rises as it moves from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line falls as it moves from left to right.

Front

What does a slope of zero indicate about a line?

Back

A slope of zero 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.
