What is the slope?

Back

The slope is a measure of the steepness of a line, indicating how much the y-value changes for a change in the x-value. It can be positive, negative, zero, or undefined.

What does a positive slope indicate?

Back

A positive slope indicates that as the x-value increases, the y-value also increases, showing a direct relationship between the two variables.

What is the slope of a horizontal line?

Back

The slope of a horizontal line is zero, meaning there is no change in the y-value as the x-value changes.

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined because the x-value does not change, leading to division by zero.

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

Back

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

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between two parallel lines and on opposite sides of a transversal. They are equal.

What are supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

What is absolute value?

Back

The absolute value of a number is its distance from zero on the number line, regardless of direction. For example, | -808 | = 808.

What does it mean for a function to be increasing?

Back

A function is increasing if, as the x-values increase, the y-values also increase.
