week 15 — Math 10

This week I learnt chapter 9– Equations of Linear Relations.

My aha moment is I solved a difficult question.

The question is Determine the angle of elevation for the line segment CD, where C(9,4) and D(-5,-2).

(hint: slope = tan. ratio) First, we just figure out what is the slope:

And then, we use the tan. ratio to figure out what is the angle of the elevation.

Then I got the answer.
