(1 point) Compute the path integral C(4x+6y)ds, where Cis the line segment in the xy-plane with endpoints P=(3,0) and Q=(0,8).(a) Find a vector parametric equation vec(r)(t) for the line segment Cso that points P and Q correspond tot=0 and t=1, respectively. Use < and > forvector notation.vec(r)(t)=(b) Using the parametrization in part (a), the line integral with respect to arc length isC(4x+6y)ds=abdtwith limitsof integration a= and b=(c) Evaluate the line integral with respect to arc length in part (b).C(4x+6y)ds=
