Step-by-step explanation:
if you need any explanation you can ask 
 
        
             
        
        
        
A. <span>2x + 5y= 10
    5y= -2x+10
</span>-> y= -2/5x+2
b. The slope is 2
c. For the y  intecpet, x is always 0
y= -2/5x+2
y= -2/5(0)+2
y=0+2
y=2
(0,2) is the y-interecpt
d. Please veiw below
 
        
        
        
2 units left would make it be 0,3 and a rotation of 90 degrees counterclockwise about the origin would make it -3,0
        
             
        
        
        
use cross products
(3r+6) *2 = 9*(2r-4)
6r+12 = 18r-36  distribute
12    = 12 r -36    subtract 6r from each side
48 = 12r  add 36 to each side
4=r  divide by 12
 
        
             
        
        
        
Y = 4x
hope that helps
