Aline passing through which of the following pairs of coordinates represents a proportional relationship?
a.
(1.3, 3.3) and (2.3, 4.3)
b.
(2.5, 5) and (3, 5.5)
c.
(1.25, 2.25) and (2.5, 5)
d.
(1.25, 2.5) and (3.75, 7.5)

D

Step-by-step explanation:

A proportional relationship is a relationship where the x and y values form equal ratios. The ratio is written as y/x.

A.  

(1.3, 3.3) and (2.3, 4.3)

3.3/1.3 = 4.3/2.3 are not equal

B.  

(2.5, 5) and (3, 5.5)

5/2.5 = 5.5/3 are not equal

C.  

(1.25, 2.25) and (2.5, 5)

2.25/1.25 = 5/2.5 are not equal

D.  

(1.25, 2.5) and (3.75, 7.5)

2.5/1.25 = 7.5/3.75 are equal.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
