What is a linear function?

Back

A linear function is a function that graphs to a straight line. It can be expressed in the form y = mx + b, where m is the slope and b is the y-intercept.

How do you find the perimeter of a rectangle?

Back

To find the perimeter of a rectangle, use the formula P = 2(length + width).

Front

What is the formula for the area of a rectangle?

Back

The area of a rectangle is calculated using the formula A = length × width.

Front

What does the line of best fit represent in a scatter plot?

Back

The line of best fit represents the trend of the data points in a scatter plot, showing the relationship between the variables.

Front

What is the maximum value of a quadratic function?

Back

The maximum value of a quadratic function occurs at the vertex of the parabola when the parabola opens downwards.

Front

How do you determine if a function is linear or non-linear?

Back

A function is linear if it can be represented by a straight line on a graph. Non-linear functions curve or change direction.

Front

What is the significance of the slope in a linear function?

Back

The slope indicates the rate of change of the function; it shows how much y changes for a unit change in x.

Front

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

Back

Use the distance formula: d = √((x2 - x1)² + (y2 - y1)²).

Front

What is a quadratic function?

Back

A quadratic function is a polynomial function of degree 2, typically in the form f(x) = ax² + bx + c.

Front

What is the relationship between the roots of a quadratic function and its graph?

Back

The roots of a quadratic function are the x-intercepts of its graph, where the function equals zero.
