1)Parallel means they have to have the same slope. Since our equation is y=2/3x+1, a line parallel to that would be(using out points) -5=2/3(-4)+b.
To find the y-intercept, solve for "b".
b=-7/3
Our equation would then be y=2/3x-7/3
2)Perpendicular lines have opposite-reciprocal slopes. our previous equation was y=2/3x+1, so our new equation would be -5=-3/2(-4)+b. Now lets solve for b.
b=-11
So our perpendicular equation would be y=-3/2x-11
Hope that was helpful. :)
 
        
             
        
        
        
Answer:
the right ones are a c and d maybe 
Step-by-step explanation:
these are probably wrong but I need my points so figure it out. 
 
        
             
        
        
        
#1,4 are biased because the number range is too wide. (include #2 if the question allows)
#1: 31-20 = 11
#2: 29-21 = 8
#3: 30-23 = 7
#4: 50-15 = 35 (OMG that's so biased!)
so if the three surveys are eliminated, then the answer to the second question is 23%.
Hope that helps :)
