In the orthonormal system (O; iβ,jβ) below, consider point A(3, β1), vector vβ(2,1), and
straight line (d).
Let (dβ) be the line of equation y = β2x + 5.
1. Show that A belongs to (dβ).
2. Draw the straight line (dβ).
3. Write a Cartesian equation of line (d).
4. What is the relative position of the lines (d)
and (dβ)? Justify your answer.
5. Write the reduced equation of the straight
line(D) defined by (A, βvβ).
6. Deduce that the two lines (D) and (d) are
perpendicular.
7. Determine the coordinates of the point of
intersection I of the two lines (d) and (D).
