x=s+t The parametric equations of a plane are y=1+t. Find a scalar equation of the plane. z=1-s

Find parametric equations for the line that passes through the point (−5, 5) and is parallel to the vector <6, −8>. (Enter your answer as a comma-separated list of equations where x and y are in terms of the parameter t.)

Find parametric equations for the line that passes through the point (−5, 5) and is perpendicular to the vector <6,−8>.  (Enter your answer as a comma-separated list of equations where x and y are in terms of the parameter t.)

Provide parametric equations for the line passing through the coordinates (1, −3, 2) and perpendicular to the the plane 4x − 3z + 7 = 0
