Answer:
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)
The first step I would take is
.. Multiply both sides of the equation by 1/4.
_____
You could start by adding 16 to both sides of the equation, to make the left side the square (2x +4)^2.
