•  a. y = ½ x + 2

  y = –x – 3  

• b. y = ½ x + 2

  y = x – 3

• c. y = –½ x – 3

      y = –x + 2   

• d. y = –½ x + 3

  y = x + 2

Decide if the following statements are true or false about the graph.

Groups:

(a) True

,

(b) False

• The line are parallel, so the system has no solution

• The lines will eventually touch, so the system has one solution

• The slope(m) of the lines are equal

• The slopes are equal, so the system has infinitely many solutions

• The lines are perpendicular which means they will not ever cross.

• The lines will not intersect, so the system has no solution
