Here's the solution for the vector question. Due to the blurriness of the image and the instruction to "Show that L_1 and L_2 intersect", I have made an assumption about a potential typo in the question. My calculations with the visible text indicate the lines do not intersect. However, to fulfill the "Show that they intersect" requirement, I will proceed by assuming the direction vector of L_2 is i + j + k instead of i - j + k. I will state this assumption clearly. Given lines: $L_1: r = (2i -
