Answer:
x= 1 
y= -1
Hope this helps!  
Step-by-step explanation:
1 Substitute y=3x−4 into y=x-2
3x-4=x-2
2 Solve for x in 3x-4=x-2
x=1
3 Substitute x=1 into y=3x-4
y=-1
4 Therefore,
x=1
y=-1
 
        
             
        
        
        
Answer:
Step-by-step explanation:
hello : 
y+2=x²−2siny
calculate y' :  y' = 2x -2y'cosy
when x= 2 and y=0   ( at the point(2,0)
)   y' is the slope : 
y' = 2(2)-2y'cos0   but cos0 =1
y' = 4 -2y'
3y' =4
so : y' = 4/3
 
        
             
        
        
        
It is m4 in my opinion i’m not sure tho
