What is the equation of the line graphed below? (3,-1)
o A. y = - 1 x
O B. y=-3x
O c. y = x
O D. y = 1/2*

Y = -1x
3 is the value of y
-1 corresponds to x

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm

5would be the answer- explanation
