Finding Slope

Front

What is the formula to find the slope of a line?

Back

The slope (m) is calculated using the formula: m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.

Front

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

Back

-1/5

Front

Find the slope of the line that passes through (-1, -9) and (5, -6).

Back

1/2

Front

What does a negative slope indicate about a line?

Back

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

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line is increasing 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 that passes through (2, 3) and (2, 5).

Back

Undefined (vertical line).

Front

Find the slope of the line that passes through (0, 0) and (4, 4).

Back

1 (positive slope).

Front

What is the slope of the line represented by the equation y = 3x + 2?

Back

3 (the coefficient of x represents the slope).
