1. The equations [x, y] = [1,2] + [3,2] and [x, y] = [7,6] + t [-6,-4] give the same line, as (7, 6) is a point on the first line, and the direction vectors are scalar multiples of each other. a. Give a third equation that generates the same line. Include a LanGraph of your line. b. Write another two different equations that give the same line as each other. Include a LanGraph of your lines.
