Across
  1. 5. the x-coordinate of the point at which the graph crosses the x-axis *y value = 0
  2. 6. ____Lines- In a plane any two oblique lines, the product of whose slope is -1. They have opposite & reciprocal slopes.
  3. 8. An equation that has no operations other than addition, subtraction, and multiplication of a variable by a constant
  4. 9. If no vertical line intersects a graph in more than point, then the graph represents a function
  5. 14. ______Form -The equation of a line in the form y=mx+b, where m is the slope and b is the y-intercept
  6. 15. ____Line- a line that runs from north to south, has an undefined slope. Equation is y = #
  7. 16. _____Form -An equation in the form y-y1=mx-x1 where (x1,y1) are the coordinates of a point on the line and m is the slope of the line.
  8. 18. _____Lines- Non-vertical coplanar lines with the same slope
  9. 19. The set of all possible output values (commonly the “y” variable) which result from using a particular function.
  10. 21. A function whose ordered pairs satisfy a linear equation.
  11. 23. ____Relation- A relation that can be graphed with a line or smooth curve
  12. 25. A set of equations with the same variables
  13. 27. An equation of y in terms of x can be rewritten so that y=f(x)
  14. 28. a way to express the input and values that are represented on a graph, usually in the form (x, y)
  15. 29. The other variable in a function, usually y, whose value depends on x.
  16. 30. ____Relation- A relation in which the domain is a set of individual points
Down
  1. 1. ____Relation- A relation that has straight line graphs
  2. 2. A relation in which each element of the domain is paired with exactly one element in the range. *every x can only have one y*
  3. 3. a set of inequalities with the same variables.
  4. 4. the y-coordinate of the point at which the graph crosses the y-axis *x value = 0
  5. 7. ____Line -a line that runs from east to west, has a slope of 0. Equation is x = #
  6. 10. In a function, the variable, usually x, whose values make up the domain
  7. 11. The ratio of change in y-coordinates to the change in x-coordinates. Often expressed as rise/run formula: m=y2-y1x2-x1
  8. 12. A set of ordered pairs.
  9. 13. How much a quantity changes on average, relative to the change in another quantity, over time
  10. 17. a mathematical sentence that uses symbols such as <, >, <, or >, to compare two quantities.
  11. 20. ____Function- A function where each element of the range is paired exactly with one element of the domain
  12. 22. The set of all possible input values (commonly the “x” variable) for which a function is mathematically defined.
  13. 24. ____Relation- Relations that are not linear
  14. 26. _____Form -A linear equation written in the form Ax+By=C, where A,B, and C are integers whose greatest common factor is 1, A > 0, and A and B are not both zero
