Slope-intercept:
y=mx+b
5x-y=9
5x=y+9
y+9=5x
y=5x-9
Slope-int: y=5x-9
        
                    
             
        
        
        
8600 because 6 is more near to zero than 8.So all the numbers after 6 become 00

Answer:
x = -10
Step-by-step explanation:
move all the constants (numbers without variables) to one side to get
-4x = 42 - 2
-4x = 40
multiply by -1
4x = -40
divide by 4
x = -10
