The roots of an equation are simply the x-intercepts of the equation.
See below for the proof that  has at least two real roots
 has at least two real roots
The equation is given as: 
There are several ways to show that an equation has real roots, one of these ways is by using graphs.
See attachment for the graph of 
Next, we count the x-intercepts of the graph (i.e. the points where the equation crosses the x-axis)
From the attached graph, we can see that  crosses the x-axis at approximately <em>-2000 and 2000 </em>between the domain -2500 and 2500
 crosses the x-axis at approximately <em>-2000 and 2000 </em>between the domain -2500 and 2500
This means that  has at least two real roots
 has at least two real roots

Answer:
The slope is -3/4
Step-by-step explanation:
We need two points to find the slope
We have one point at (0,5) and we have one point at (4,2)
We can use the slope formula
m = (y2-y2)/(x2-x1)
    = (2-5)/( 4-0)
    = -3/4
The slope is -3/4
 
        
                    
             
        
        
        
The confirmed correct answer is -9%. Trust me.
