Step -by -step explanation :
The general form of equation of a line that will pass through the three points is:
y=mx+c
where m is the gradient and c is the y-intercept
Now, find the gradient.

Take,

Answer:

Step-by-step explanation:
we know that
The angle x belong to the III quadrant -----> given problem
step 1
Find the angle x

Remember that the angle x belong to the III Quadrant
so

step 2
Find angle x/2

step 3
Find tan(x/2)

Sin = Opposite/Hypotenuse
Cos= Ajacent/Hypotenuse
Tan= Opposite/Adjacent
