Slope of Lines Flashcard

Front

Slope in the graph is ________.

Back

The slope can be positive, negative, zero, or undefined depending on the direction of the line.

Front

Find the slope of the line that is parallel to y = -3x + 7.

Back

The slope of a line parallel to y = -3x + 7 is -3.

Front

What does a negative slope indicate about a line?

Back

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

Front

What does a positive slope indicate about a line?

Back

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

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

Which equation represents a line with a slope of 2?

Back

y = 2x + b, where b is any real number.

Front

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

Back

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

Front

What does the slope-intercept form of a line look like?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

If a line has a slope of 3, what is the angle of inclination?

Back

The angle of inclination can be found using tan(θ) = slope, so θ = arctan(3).
