A vector equation for the line that passes through the point (−2,4) and is parallel to the line x=[31]+t[43] is

A vector equation for the line that passes through the point (−2,4) and is perpendicular to the line ????=[31]+????[43] is

What is a general equation for the line with vector equation ????=[31]+????[43]x=[31]+t[43]?

The line with equation ????=[31]+????[−12 ????]is the same as the line given by the equation ????=[31]+????[43] if and only if ????=?.

The line with equation ????=[−13 ????] +t[8 6] is the same as the line given by the equation ????=[31]+????[43] if and only if b=?.

(For what value of b is the point (−13,????) on the second line?)
