Answer:
y= 2x-1/2 is     x=.5 y + .25
2x-3y=4  is     x = 1.5y + 2
Step-by-step explanation:
pretty sure thats it
 
        
             
        
        
        
You form a rhombus.
Draw an equilateral triangle, and then mirror it around its base. All the sides are clearly equal, because they are all sides of the same equilateral triangle.
Moreover, the top and bottom angle are 60°, because they are angles of an equilateral triangle, while the left and right angles are 120, because they're 60+60 angles.
 
        
             
        
        
        
2+4a=-10
First, subtract 2 from both sides.
4a=-12
Then divide 4 from both sides.
a=-3
hope it helps!
