Find Slope

Front

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

Back

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

Front

Calculate the slope of the line that passes through the points (1, -8) and (-3, 0).

Back

-2

Front

What is the slope of the line that passes through the points (5, -11) and (25, 9)?

Back

1

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

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 type of slope does the line y = 3 represent?

Back

The slope is 0 (horizontal line).

Front

What type of slope does the line x = -2 represent?

Back

The slope is undefined (vertical line).

Front

If the slope of a line is -1, what does this tell you about the line's direction?

Back

The line falls at a 45-degree angle from left to right.
