  1. 6. linear equations are often written in
  2. 8. when points on a graph lie along it its called a linear relation
  3. 9. can be shown in a table, mapping, graph, equation
  4. 10. linear relations can be represented by it
  5. 11. the slopes of parallel lines are
Down
  1. 1. to write a linear equation given the slope of the line(m) and a point that it passes through(x-y)
  2. 2. the slopes od perpendicular lines are
  3. 3. also refered to as a root,zero, or solution to the equation
  4. 4. shows the relationship between two variables, sketch the three possible relationships below
  5. 5. to a system of linear inequations is the set of ordered pairs that satisfy all the linear equations the solution can be shown by graphing
  6. 7. similar to a linear equation however with an inequality symbol instead
