Answer:
y= -2/3x+490
slope: -2/3
y-intercept: 490
Step-by-step explanation:
Y-intercept form is y=mx+b, so you would first subtract 2x from both sides to get 3y= -2x+1,470. Then you divide both sides by 3, to get y= -2/3x+490. -2/3 is in the place of m, so it is the slope, and 490 is in the place of b, so it is the y-int.

D because a rational number can be converted into a fraction and the square root of 5 cannot be covert into a fraction because it equals 2.2
        
             
        
        
        
190
You add everything together
Then, divide by however many numbers you have
210+160+200
570 / 3
 190
