Answer:
the slope of y=3x/7+4/7 is M=3 over 7
 
        
             
        
        
        
-2x^2+8x+5 is the standard form
        
             
        
        
        
So first put this in slope intercept form, y=mx+b. subtract x from both sides so now you have 3y=-x+3 and to get y by itself divide both sides by 3 so now you have y=(-x/3) +1 or y=-1/3(x)+1 the slope is m and the y-intercept is b so the slope is -1/3 and the y-intercept is 1
