  1. 2. of the graph of a linear inequality is a line in the coordinate plane. It separates the solutions of the inequality from the non solutions.
  2. 4. the possible
  3. 5. a positive angle measuring less than 90 degrees.You will use this term in geometry.
  4. 6. every number in an iternal with a single value. The graph of a __________can look like the step of a staircase
  5. 9. is the line that divides a figure into two parts that are mirror image. runs through the the middle of the parabola.
  6. 10. the sum of the data values divided by the number of data values is the mean.This is also called the average
  7. 12. when a number has two real roots, the positive root is called the _______. A radical sign indicates this.
  8. 15. a function is the input value for which the value of the function is zero. A____ of an equation is a value that makes the equation true.
  9. 16. the graph of a quadratic function. When you graph the line will make a u-shape
  10. 17. the is the distance between the center of the circle and any point on the circumference. This is half of the circumference.
  11. 18. is a quality whose value does not change. for example x+5=9, 5 and 9 are constants.
  12. 19. the minimum value of a function y=f(x) is the least y-value of the function. It is the y-coordinate of the lowest point on the graph.
  13. 20. are lines that intersect to form right angles. In the coordinate plane, _______ have slopes with product -1.
Down
  1. 1. the horizontal line through the average of the maximum and the minimum values. You can find this going right through the middle of you graph.
  2. 3. the____of a relation is the set of all inputs, or the ordered pairs.
  3. 7. two equation whose solutions are the same. These two equations will equal each other in the end.
  4. 8. is the middle value in a data set. If the data set contains an even number of values, the ___ is the mean of two middle values.
  5. 11. flips the graph of a function across a line, such as the x or y axis. Each point on the graph of the refelction as is the corresponding point on the graph of the original function.
  6. 12. are coplanar lines that do not intersect. These lines lay right across from each other. An example would be railroad tracks
  7. 13. is a transformation that turns a figure about a fixed point called the center of rotation. Will rotate either up or down.
  8. 14. is a values substantially different from the rest of the data set. For example is you have 56,64,73,59,98,65,59) the outlier would be 98.
