Answer:
A. y = ½x
Step-by-step explanation:
Equation of a proportional relationship is given in the form of y = mx
Where,
m = constant of proportionality or rate of change or slope = y/x
This, using any given pair of values on the table, say (2, 1),
Constant of proportionality (m) = y/x = 1/2 = ½
To write the equation, substitute m = ½ into y = mx
Thus:
y = ½x
