Answer:
angle Y= 60 degrees
Step-by-step explanation:
angle S + angle Y = 90 degrees because they are complementary
Y = 90 - S
angle S = 4(Y)-210
substitute for Y
S = 4(90 - S) - 210
S = 360 - 4S - 210
reduce
5S = 150
S = 30
Y = 90 - 30 = 60
 
        
             
        
        
        
The value would have x being equal to 3
        
                    
             
        
        
        
Answer:
y=2x-9
Step-by-step explanation:

y-3=2(x-3)
y-3=2x-6
y=2x-9
y-intercept=-9
slope=2x
