What is the slope of a line?

Back

The slope (m) of a line is a measure of its steepness, calculated as the change in y divided by the change in x (rise/run).

Front

What is a function?

Back

A function is a relation where each input (x-value) has exactly one output (y-value).

Front

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

Back

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

Front

What does it mean for a set of values to be a function?

Back

A set of values is a function if no x-value is repeated, meaning each input corresponds to one unique output.

Front

What is the formula for simplifying (x - a)²?

Back

(x - a)² = x² - 2ax + a².

Front

What are the roots of a function?

Back

The roots (or zeros) of a function are the values of x where the function equals zero (f(x) = 0).

Front

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, b) in the equation y = mx + b.

Front

What is the vertex of a parabola?

Back

The vertex is the highest or lowest point of a parabola, depending on its orientation.

Front

How do you determine if a quadratic equation has real roots?

Back

A quadratic equation has real roots if the discriminant (b² - 4ac) is greater than or equal to zero.

Front

What is the standard form of a linear equation?

Back

The standard form of a linear equation is Ax + By = C, where A, B, and C are integers.
