In form
ax+by=c
slope=-a/b
y intercpept=c/b
so
-3x-4y=-12
a=-3
b=-4
c=-12
slope=-(-3)/-4=3/-4=-3/4
yint=-12/-4=3
slope=-3/4
yint is 3
        
                    
             
        
        
        
okay put heat on the left
Step-by-step explanation:
 
        
             
        
        
        
x = -8
Step-by-step explanation:
Step 1: Subtract 1 from both sides

Divide both sides of the equation by -10

 
        
                    
             
        
        
        
8/(9/6)
(8/1)/(9/6)
(8/1)*(6/9)
48/9
5 1/3
