  1. 2. The point on a coordinate plane where the x-axis and y-axis intersect. It is represented by the coordinates (0,0).
  2. 3. An expression or equation in which the highest power of a variable has exponent 2.
  3. 6. 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.
  4. 8. A constant that a variable or expression is multiplied by.
  5. 9. Going from side to side, like the horizon.
  6. 11. The set of inputs (x-coordinates) of a relation or function.
  7. 12. Element in a sum, difference, or sequence.
  8. 14. An expression that is multiplied by another expression, or that can be multiplied by another expression to produce a specified result.
  9. 15. A mathematical sentence that uses one of the symbols <, >, ≤, or ≥.

  1. 1. Two fractions are equivalent if they have the same numerical value. Two equations or inequalities are equivalent if they have the same solution se
  2. 4. The speed at which a variable changes over a period of time. This is given by the change in the variable divided by the change in (amount of) time.
  3. 5. A relation in which no x-coordinate appears in more than one (x,y) ordered pair. This means you can think of a function as a transformation that takes each x-coordinate to its single corresponding y-coordinate.
  4. 7. Two lines are parallel if they always have the same distance between them, so they never intersect. If two lines are parallel, they have the same slope.
  5. 10. A single fixed number (unlike a variable, whose value can vary).
  6. 13. The set of outputs (y-coordinates) of a relation or function.
