5x + 10y = 360
y = 2x + 1
5x + 10*(2x + 1) = 360
5x + 20x + 10 = 360
25x = 350
x = 14
y = 2x + 1
y = 2*14 + 1
y = 29

Answer: 261 
Step-by-step explanation:
You use PEMDAS to solve this problem 
you first do the Parenthesis (p) 
33+6(2+36) 
33+6 (38)
We then multiply first (M) 
 33 + 6(38) - we know that 8 times 6 is 48 ; 6 times 3 is 18 +4 because we brought down the 4 from 48 to 3. which will be equal to 228
33 + 228 
261
 
        
             
        
        
        
So slope intercept form is y=mx+b
m=slope b=y intercept
convert current equation to slpe intercept
y-4=x-8
add 4 to both sides
y=x-4
