What does the slope represent in a linear equation?

Back

The slope represents the rate of change of the dependent variable with respect to the independent variable.

Front

What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables.

Front

What does it mean if a system of equations has infinitely many solutions?

Back

It means that the equations represent the same line, and any point on that line is a solution.

Front

What is the difference between mean and median?

Back

Mean is the average of a set of numbers, while median is the middle value when the numbers are arranged in order.

Front

How do you find the vertex of a quadratic function in standard form?

Back

The vertex can be found using the formula x = -b/(2a) for the quadratic equation ax² + bx + c.

Front

What is the factored form of a difference of squares?

Back

The factored form of a difference of squares is (a - b)(a + b).

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the value of y when x = 0, representing the starting point of the line on the y-axis.

Front

What does it mean for a value to be a local minimum in a quadratic function?

Back

A local minimum is the lowest point in a specific interval of the function.

Front

How do you determine if a quadratic function opens upwards or downwards?

Back

If the coefficient of x² (a) is positive, the parabola opens upwards; if negative, it opens downwards.

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is given by the formula A = 1/2 * base * height.
