Question

Select all the correct answers. Identify all the lines on the graph with unit rates that are less than 2 and greater than the unit rate of the relationship in the table. y y- B 7 3 5 6 6 3 N х 2 07 4 5 6 7 8

Answer 1

step 1

Find the unit rate of the table

take two points

(7,8) and (21,24)

so

m=(24-8)/(21-7)

m=16/14

m=8/7

m=1.14

step 2

Find the unit rate of each line

These lines represent a proportional relationship (because passes through the origin)

that means

we need only one point to calculate the unit rate

Line 1

(1,3) -------> m=3/1=3

Line 2

(1,2) ------> m=2

Line 3

(1,1.5) -----> m=1.5

Line 4

(1,1) ------> m=1

therefore

answer is Line 3

because the unit rate is less than 2 and greater than 1.14
