What is a linear inequality?

Back

A linear inequality is a mathematical statement that relates a linear expression to a value using inequality symbols (e.g., <, >, ≤, ≥). It represents a region of the coordinate plane.

How do you find the solution to a system of equations?

Back

To find the solution to a system of equations, you can use methods such as substitution, elimination, or graphing. The solution is the point where the equations intersect.

What does it mean to factor a polynomial?

Back

Factoring a polynomial means expressing it as a product of its factors, which are simpler polynomials. For example, x² + 5x - 24 can be factored into (x + 8)(x - 3).

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the change in y divided by the change in x (rise/run). It indicates how much y changes for a unit change in x.

Front

What is a y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis. It is the value of y when x = 0 in the equation of the line.

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, and A should be non-negative.

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). A relation can have multiple outputs for a single input.

Front

How do you graph a linear inequality?

Back

To graph a linear inequality, first graph the corresponding linear equation as a solid line (for ≤ or ≥) or dashed line (for < or >). Then shade the region that satisfies the inequality.

Front

What is the quadratic formula?

Back

The quadratic formula is used to find the solutions of a quadratic equation ax² + bx + c = 0. It is given by x = (-b ± √(b² - 4ac)) / (2a).

Front

What is the vertex of a parabola?

Back

The vertex of a parabola is the highest or lowest point on the graph, depending on whether it opens upwards or downwards. It can be found using the formula (-b/(2a), f(-b/(2a))).
