What is the slope of a line that passes through two points?

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1). It represents the steepness of the line.

Front

What is the equation for the axis of symmetry in a quadratic function?

Back

The axis of symmetry for a quadratic function in the form y = ax^2 + bx + c is given by x = -b/(2a).

Front

What is the range of a function?

Back

The range is the set of all possible output values (y-values) of a function.

Front

How do you represent inequalities involving two variables?

Back

Inequalities can be represented in the form ax + by <, >, ≤, or ≥ c, where a, b, and c are constants.

Front

What does it mean for a function to be quadratic?

Back

A quadratic function is a polynomial function of degree 2, typically in the form y = ax^2 + bx + c.

Front

What is the vertex of a parabola?

Back

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

Front

How do you find the y-intercept of a linear equation?

Back

The y-intercept is found by setting x = 0 in the equation and solving for y.

Front

What is the difference between a function and a relation?

Back

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

Front

What is the standard form of a linear equation?

Back

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