 The vertical intercept of line (2) on the above graph is:

      
       A) 8      
       B) 12
       C) 16
       D) 24
      

 

227)       If the equation y = 5 + 6x was graphed, the:

      
       A) slope would be -5.
       B) slope would be +5.
       C) slope would be +6.
       D) vertical intercept would be +.6.
      

 

228)       If the equation y = 15 - 4x was plotted, the:

      
       A) vertical intercept would be -4.  
       B) vertical intercept would be +4.
       C) vertical intercept would be +9.
       D) slope would be -4.
      

 

229)       If the equation y = -10 + 2.5x was plotted

      
       A) the vertical intercept would be -10. 
       B) the slope would be + 2.5.
       C) it would graph as an upsloping line.
       D) all of these are correct.
      

 

230)       Refer to the graph. The movement from line A to line A' represents a change in:

      
       A) the slope only.     
       B) the intercept only.
       C) both the slope and the intercept.
       D) neither the slope nor the intercept.
      

 

231)       In the below diagram variables x and y are:

      
       A) both dependent variables.  
       B) directly related.
       C) inversely related.
       D) unrelated.
      

 

232)       In the below diagram the vertical intercept and slope are:
 


 

      
       A) 4 and -1¹/₃respectively.      
       B) 3 and -1¹/₃respectively.
       C) 3 and +³/₄respectively.
       D) 4 and +³/₄respectively.
