Answer:
→For,a linear expression
y= k x,
Constant , k is the constant of variation.
→→In the statement, it is given that, The acceleration due to gravity is the constant of variation.
→So,the linear expression changes to
y=g x,where g, is constant of proportionality.
→→acceleration due to gravity of a falling object= +9.8 m/s²,because the object is falling downwards,work is not done against the gravity.
Option B: 9.8
