Find the slope and inclination of the line passing through each of the following two points （1）C(10,8)、D(4,-4) (2) P (0,0) Q (- 1, radical 3) (3) M (- radical 3, radical 2) n (- radical 2, radical 3)

Find the slope and inclination of the line passing through each of the following two points （1）C(10,8)、D(4,-4) (2) P (0,0) Q (- 1, radical 3) (3) M (- radical 3, radical 2) n (- radical 2, radical 3)

(1) Slope k = (- 4-8) / (4-10) = 2, Tan θ = 2, tilt angle θ = arctan 2;
(2) Slope k = (√ 3-0) / (- 1-0) = - √ 3, Tan θ = - √ 3, tilt angle θ = 2 π / 3;
(3) Slope k = (√ 3 - √ 2) / (- √ 2 + √ 3) = 1, Tan θ = 1, tilt angle θ = π / 4
