1. The problem statement, all variables and given/known data Find the angle of inclination of each of the following lines. i) r = (2,-6) + t(3,-4) ii) r = (6,1) + t(5,1) B) prove that the tangent of the angle of inclination is equal to the slope of the line. 2. Relevant equations N/A 3. The attempt at a solution I know that the angle ø, 0° < ø < 180°, that a line makes with the positive x-axis is called the angle of inclination of the line. However, I don't have any idea how to approach this question.
