What happens to the graph of y=12x+5 when the equation of the line becomes y= 4x+5
a) the line is 4 times as steep
b) the line is 1/4 as steep
c) the line is 3 times as steep
d) the line is 1/3 as steep

I believe that the answer would be D) the line is 1/3 as steep. Since the slope was 12 in the first equation, and the slope was 4 in the second equation, I can compare them in a fraction 4/12=1/3. 12 is three times larger than 4, and 4 is 1/3 of 12.

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
