Daily Objective: Review of slopes of line; slopes of parallel and perpendicular lines.




Quiz
1) Find the slope of the line. (1,2) (3,1)
2) Find the point of interception. (0,3) (1,0)& (-3,-1) (-2,-4)
3) Find the point of interception. (-3,-2) (1,-2) & (3,2) (-1,-2)
Answer Key
1)


     (1,2) (3,1)   1-2/ 3-1=  -1/2
                         

    Slope= -1/2

3)                       
 (-3,-2)(1,-2) 
-2-(-2)/1-(-3)= 0/4
(3,2)(-1,-2)
-2-2/-1-3= -4/-4 or 1
