  2. 3. y=mx+b
  3. 7. Equation, an equation whose solutions form a straight line on a coordinate plane and is in the form of y = mx + b.
  4. 8. the first number in an ordered pair; it tells the distance to move right or left from the origin (0,0).
  5. 10. y = mx + b, b0; y = kx
Down
  1. 1. A ratio that compares the amount of change in a dependent variable to the amount of change in an independent variable.
  2. 4. y=kx
  3. 5. the y-coordinate of the point where the graph of a line crosses the y-axis. It is the point (0, b). In the table it is the point where x = 0.
  4. 6. A measure of the steepness of a line on a graph; the rise divided by the run.
