If  5 = 6 , than 4 =7
so, line L // m
        
             
        
        
        
For number 5 you are just multiplying by 4.5
        
             
        
        
        
To find the X value of the solution, you would set the two equations equal to each other bu substitution:
if <span>y = -2x + 5 and y = 3x - 2, 
</span>-2x + 5 must be equal to 3x - 2
solve for x... you should get 7/5
then, plug that into one of the original equations as X and you would get the Y value, 11/5
This point, (7/5,11/5) is where the two lines cross
