Question

Which equations have a lower unit rate than the rate represented in this table?

Answer 1

Answer:

A and D

Find the unit rate of the data in the table:

y = kx

2 = 6k

k = 2/6

k = 1/3

The equation is:

y = 1/3x

Compare this with the others:

A. 3/11 < 1/3 = 3/9      ⇒ yes

B. 2/5 > 1/3 = 2/6      ⇒ no

C. 9/23 > 1/3 = 9/27  ⇒ no

D. 4/13 < 1/3 = 4/12    ⇒ yes

E. 3/8 > 1/3 = 3/9       ⇒  no

Answer 2

Answer:

• A and D

Step-by-step explanation:

Find the unit rate of the data in the table:

• y = kx
• 2 = 6k
• k = 2/6
• k = 1/3

The equation is:

• y = 1/3x

Compare this with the others:

• A. 3/11 < 1/3 = 3/9      ⇒ yes
• B. 2/5 > 1/3 = 2/6      ⇒ no
• C. 9/23 > 1/3 = 9/27  ⇒ no
• D. 4/13 < 1/3 = 4/12    ⇒ yes
• E. 3/8 > 1/3 = 3/9       ⇒  no
