Use linear regression to find the linear equation for Torque

Use linear regression to find the linear equation for Torque vs. Displacement for the following data: None of the above. T(in-lbf/100psi) = 15.95 [(in-lbf/100 psi)/(cu-in/rev)]. d(cu-in/rev) + 0.43 (in-lbf/100 psi) T = 15.95 [(in-lbf/100 psi)/(cu-in-rev)] d(cu-in/rev) T (in-lbf/100psi) = 1 [(in-lbf/100 psi)/(cu-in/rev)]. d(cu-in/rev) + 0.43 (in-lbf/100 psi)

Solution

By plotting the graph of T vs d for the given option, the closest one is T = 15.95d
