Down
- 1. An image formed by plotting the solutions to an equation or inequality, or some other set of pairs of numbers, on a coordinate plane. To graph an expression containing the variable x, set y equal to that expression.

- 12. A numerator divided by a denominator.
- 14. The vertical line running through the origin on a coordinate plane.
- 17. A joint frequency divided by the total of its row or column in a two-way frequency table.
- 18. 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.
