Algebra Terms

3. A mathematical sentence that uses one of the symbols <, >, ≤, or ≥.
5. A number that measures how steep a line is. It shows the amount of change in the height of the line as you go 1 unit to the right. The slope of the line y=mx+b is m.
10. The set of outputs (y-coordinates) of a relation or function.
12. y−y1=m(x−x1)
13. For a linear equation, the form Ax+By=C where A, B, and C are constant
14. A line that you can flip (or reflect) a graph across that results in the same graph.
15. All solutions to an equation, inequality, or system.
16. The values of x where a polynomial is zero. These are the x-coordinates of the x-intercepts of the polynomial’s graph.

1. The point where a parabola crosses its axis of symmetry, or an end of a side of a polygon, or the corner point of an angle.
2. A quadratic equation in the form y=a(x−h)2+k.
4. The set of inputs (x-coordinates) of a relation or function.
6. Rewriting an expression as a product.
7. The point on a coordinate plane where the x-axis and y-axis intersect. It is represented by the coordinates (0,0)
8. The values of x where an expression is zero. These are the x-coordinates of the x-intercepts of the expression’s graph. For a polynomial expression, these are usually called roots.
9. An expression or equation in which the highest power of a variable has exponent 2.
11. an algebraic expression that has three non-zero terms and has more than one variable in the expression
12. Two lines that intersect at a 90-degree angle
