20 points! Martin purchased a condo below market value in 2001. He paid $92,500 for the condo even though the market value of the condo was much higher. In 2014, Martin transferred to another city for work and had to sell his condo. The market value of his condo increased over time, as shown in the graph below, where the y-axis represents the market value of the condo, in dollars, and the x-axis represents the number of years since 2001.

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

150
