Look at the following pairs of numbers (x, y).
(3, 16.5), (4, 22), (5, 27.5), (6, 33)
Which could be the relationship between x and y?
©
A. y = 4.5 x
O
B. y = 5.5 x
O
C. y = 6.5 x
O
D. y = 7.5 x

Step-by-step explanation:

Taking the first coordinate point (3,16.5)

where x= 3 and y= 16.5

optionB

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

step-by-step explanation:
