Find Slope

Front

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

Back

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

Front

Find the slope between the points (2, 3) and (5, 11).

Back

Slope = (11 - 3) / (5 - 2) = 8 / 3

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 is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

Find the slope of the line represented by the equation y = 4x + 1.

Back

Slope = 4

Front

Find the slope of the line represented by the equation y = -2x + 3.

Back

Slope = -2

Front

If the slope of a line is 1/2, what does this mean in terms of rise and run?

Back

For every 2 units moved horizontally (run), the line rises 1 unit (rise).

Front

What is the slope of the line represented by the equation y = 0?

Back

Slope = 0 (horizontal line).
