1. The \(y\)-axis is the vertical reference line in a 2D Cartesian coordinate system
6. The x-axis is the horizontal line on a two-dimensional Cartesian coordinate system
8. A y-intercept is the point where a graph intersects the vertical \(y\)-axis, defined by the coordinates
9. A function is a mathematical relationship where every input (\(x\), or domain) corresponds to exactly one output
10. measures the steepness and direction of a line, calculated as the ratio of vertical change to horizontal change ("rise over run")
13. A rational number is any number that can be expressed as a fraction
14. root. A square root of a number \(x\) is a value \(y\) that, when multiplied by itself, equals the original number
15. of or in or along or relating to a line; involving a single dimension.

2. real numbers that cannot be expressed as a simple fraction
3. A y-intercept is the point where a graph intersects the vertical \(y\)-axis, defined by the coordinates
4. mathematical models where the output is not directly proportional to the input
5. represents a part of a whole, consisting of a numerator (top, parts considered) and a denominator (bottom, total equal parts)
7. The x-intercept is the point(s) where a graph or equation intersects or crosses the horizontal x-axis.
11. The domain is the set of all possible input (\(x\)) values for which a function is defined
12. range is the set of all possible output (\(y\)) values.
