Unit 4 Algebra 1

6. Function A function whose graph is a solid, unbroken line or curve.
8. Inequality A mathematical sentence that uses symbols like \(<, >, \leq,\) or \(\ge \) instead of an equal sign.
10. The set of all possible output values (typically \(y\)-values).
11. The point where a graph crosses the \(x\)-axis (\(y = 0\)); also known as a Zero.
13. A method of solving a system by adding or subtracting equations to remove a variable.
14. Variable The variable representing output values (usually \(y\)); it "depends" on the input.
15. Function A function whose graph consists only of individual, isolated points.

1. The point where a graph crosses the \(y\)-axis (\(x = 0\)).
2. A method of solving a system by replacing one variable with an equivalent expression.
3. Form y=mx+b
4. A relation where each input has exactly one output.
5. The set of all possible input values (typically \(x\)-values) for a function.
7. The measure of a line's steepness, often called "rise over run" or the rate of change.
9. Variable The variable representing input values (usually \(x\)); it "controls" the outcome.
12. Form Ax+By=C
