Identifying Slope From a Graph

Front

Slope is ________.

Back

A measure of the steepness or incline of a line, which can be positive, negative, zero, or undefined.

Front

What does a positive slope indicate?

Back

A positive slope indicates that as the x-value increases, the y-value also increases.

Front

What does a negative slope indicate?

Back

A negative slope indicates that as the x-value increases, the y-value decreases.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is zero.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

How do you calculate the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

Find the slope of the line passing through the points (2, 3) and (5, 7).

Back

Slope = (7 - 3) / (5 - 2) = 4 / 3.

Front

What type of slope does the line y = 2x + 1 have?

Back

Positive slope.

Front

What type of slope does the line y = -3x + 4 have?

Back

Negative slope.

Front

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

Back

Zero slope.
