  1. 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.
  2. 8. Rewriting an expression as a product.
  3. 10. A mathematical sentence with an equals sign (like 3x+5=11).
  4. 11. The distance a number is from 0.

  7. 9. The set of outputs (y-coordinates) of a relation or function.
  8. 12. 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.
