Answer:
Part 1) 
Part 2) 
Step-by-step explanation:
Part 1) 
we know that
The equation of the line in slope intercept form is equal to

we have

Isolate the variable y
subtract 2x both sides

Divide by B both sides

Part 2) 
we know that
The equation of the line in slope intercept form is equal to

we have

Isolate the variable y
subtract 2x both sides

Divide by 8 both sides

Simplify

Step-by-step explanation:
 
        
                    
             
        
        
        
For number 22:
7y=8x-14 ; y=6
Plugging in y, we get:
7*6 = 8x - 14
42 = 8x-14
56 = 8x
x = 7
Comparing answers, x is, indeed 7.
