Answer:
 <em>k = - 7.5 </em>
Step-by-step explanation:
Slope "m" of a line through points 
(  ,
 ,  )
 ) 
(  ,
 ,  )
 ) 
is m =  
 
Slopes of perpendicular lines are opposite reciprocal:  
  = - 1
 = - 1 
~~~~~~~~~~~~~~~ 
The slope of a line through points (0, 7) and (2, 10) 
 =
 =  =
 =  
 
Slope of perpendicular line through points (3, 5) and (k, 12) is  =
 =  
 
or  =
 =  
 
 =
 =  
 
2(k - 3) = - 21 
k - 3 = - 10.5 
<em>k = - 7.5</em> 
 
        
             
        
        
        
Answer:
When you have a equation you can easily find the x value and y value which you can assume the x-intercept is (x,0). and y-intercept is (0,y)
