Exercise 13B questions 4, 5, 6, 7a

Complete the following questions before our next class.

Exercise 13A questions 1–4, 5ac, 6ab

In class we looked at the question below.

1. Find the distance of the point A(1, 3) to the line y = 2x − 2.

Here’s another to look at tonight.

2. Find the distance of the point A(4, –1) to the line \[\vec{r}=\begin{bmatrix}2\\5\end{bmatrix}+\lambda \begin{bmatrix}-2\\1\end{bmatrix}.\]

While solving these, think about how a “purely vector” approach could be used here, and we’ll look at that sort of solution to these questions in class tomorrow.
