The vector ai+bj is perpendicular to the line ax+by = c. Use this fact to find an equation of the line through P perpendicular to v. Then draw a sketch of the line including v as a vector starting at the origin.P(-1,-8) v= -5i+j

Determine whether the lines L1 and L2 given by the vector equations are parallel, perpendicular, or neither. L1: r(t) = (-1 + 4t)i + (5 + t)jL2: r(s) = (3 + 2s)i + (2 - 8s)j   If the lines are not parallel, find their point of intersection. (If the lines are parallel, enter PARALLEL.)
