A=(vf-vi)/t solve for tsolve for vi solve for vf

Solve for ' t ' :                           A = (vf - vi) ) / t

Multiply each side by ' t ' :       A t  =  (vf - vi)

Divide each side by  ' A ' :         t  =  (vf - vi) / A 
                                         

Solve for ' vi ' :                         A = (vf - vi) ) / t

Multiply each side by ' t ' :      A t = vf - vi

Subtract ' vf ' from each side :    A t - vf  =  - vi

Multiply each side by  ' -1 ' :       - A t + vf  =  vi 

Solve for  ' vf ' :                       A = (vf - vi) ) / t

Multiply each side by ' t ' :    A t  =  vf - vi

Add ' vi ' to each side:          A t + vi  =  vf

Alinear relationship would look like a straight line on the graph. it could have a positive negative or 0 slope. so it could be a line potentially going in any direction but it must be perfectly straight.
