Answer:
Step-by-step explanation:

Plot the points(0 ,-4) , (5 , -5) and (-5 , -3 ) in the graph and join the points.
 
        
             
        
        
        
You would plug in 3 for x, which gives you y = 10(3) + 2, and then you would use PEMDAS, which means you multiply 10 with 3 and then add two which is 32. Therefore y would equal 32. :D :D
        
                    
             
        
        
        
Group and factor
group y's with y's and z's with z's
(y²-10y)+(10z-yz)
factor
y(y-10)+z(10-y)
force undistribute -1
-y(10-y)+z(10-y)
factor
(10-y)(-y+z)
(z-y)(10-y) or
(y-z)(y-10)
