Given three equations : 1) 6y = -3x + 2
2) 4y = -2x + 3
3) -2y = x

A. All three equations have a different rates of change.

B. The rate of change of the first equation is the highest.

C. All three lines are parallel.

D. Equations 1 and 2 have equal slopes

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

answer: -0.5 would be the most likley outcome
