Question

Can someone help me pls its due today

Answer 1

5/2 = 2.5

2/3 = 0.66667

Explanation:

13) From graph

for A Constant of proportionality is 10/4 = 20/8 = 5/2 = 2.5

for B Constant of proportionality is 8/12 12/18 = 2/3 = 0.66667

14) for Object C unit rate / Constant of proportionality is

y / x = 7.5/5 = 15/10 = 30/20 = 1.5

unit rate = 1.5

Object C rate is in between A and B 's rate

A > C > B

Answer 2

13)

Line A - slope/constant of proportionality = 5/2

Line B - slope/constant of proportionality = 2/3

14)

unit rate = 3/2 or 1.5

The unit rate, 3/2, is greater than line B's unit rate but is less than line A's unit rate.

Explanation:

To find the constant of proportionality for question 13 you use the graph. k = y/x so you find the point at (4, 10) and you go up 10 (y) and over 4 (x). So now you have 10/4 and then you simplify to 5/2. Use the same method for line B to find the slope. Now for question 14 you subtract 10 - 5 to get 5 which is your x and 15- 7.5 to get 7.5 which is the y. So this is now 7.5/5 (y/x) or 3/2. 3/2 is less than 5/2 and greater than 2/3.

Thank you so much!!! Hope this helps!!!
