Answer:
T = 0.34r³
Step-by-step explanation:
Given that T is directly proportional to r³ then the equation relating them is
T = kr³ ← k is the constant of variation
To find k use the condition T = 21.76 when r = 4 , then
21.76 = k × 4³ = 64k ( divide both sides by 64 )
0.34 = k
T= 0.34r³ ← equation of variation

One of the many ways of writing the equations of lines is the slope - intercept form. This is generally expressed as,
y = mx + b
where m is the slope and b is the y-intercept.
Substituting the known values of m and b to the equation above,
y = -2x + 4
Thus, the answer is letter A.
