Please help! tell whether x and y are proportional. if so, identify the constant of proportionality
1. y= 1/2x
2. y=2x + 7
3. x= y + 2
thanks

y = (1/2)x is proportional; (1/2)

Step-by-step explanation:

1. y= 1/2x   Proportional; constant of proportionality is 1/2.

2. y=2x + 7   Not proportional because of the non-zero y-intercept.

3. x= y + 2    Not proportional (same a reason as for #2)

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
