[ Answer ]

[ Explanation ]
- Simplify: -0.8b + 4.1c - (-3.2b) - 0.1c
-----------------------------------
-0.8b + 4.1c + 3.2b - 0.1c
-0.8b + 3.2b + 4.1c - 0.1c
- Add Similar Elements: -0.8b + 3.2b = 2.4b
2.4b + 4.1c - 0.1c
- Add Similar Elements: 4.1c - 0.1c = 4c
2.4b + 4c

a) The equation of line k is:

b) The equation of line j is:

The equation of a line, in <u>slope-intercept formula</u>, is given by:

In which:
- m is the slope, which is the rate of change.
- b is the y-intercept, which is the value of y when x = 0.
Item a:
- Line k intersects line m with an angle of 109º, thus:

In which
and
are the slopes of <u>k and m.</u>
- Line k goes through points (-3,-1) and (5,2), thus, it's slope is:

- The tangent of 109 degrees is

- Thus, the slope of line m is found solving the following equation:






Thus:

It goes through point (-2,6), that is, when
, and this is used to find b.





Thus. the equation of line k, in slope-intercept formula, is:

Item b:
- Lines j and k intersect at an angle of 90º, thus they are perpendicular, which means that the multiplication of their slopes is -1.
Thus, the slope of line j is:


Then

Also goes through point (-2,6), thus:



The equation of line j is:
