Show the steps as I am not sure much about this unit.

1. A line 4 passes through the points A(2, 3) and B(2, 1). a. Find a vector equation for the line 4. b. Sketch 4 and the closed triangle that represents your vector equation. c. Write a vector equation for a line 12 that has slope-intercept form y = 3x + 4. d. Use the vector or parametric equations to determine the point of intersection (if there is one) of 4 and 4 .
