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

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

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

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

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

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

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

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

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

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