Pls help me do my math problem

3,6,9

1,2,3

Step-by-step explanation:

because the dots go from number to number on the coordinate plane and the 3,6,9 is the top of the graph it would be in and the 1,2,3 is the bottom part

it goes up by 3 so

y= x (multiplied by) 3

x/3-10=8

x/3=18

x=48

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
