The formula of a slope:

We have the points A(-6, 6) and B(12, 3). Substitute:

Therefore we have
.
Put the coordinates of the point B to the equation:

<em>add 2 to both sides</em>

Answer:

Well the y-intercept is +2
And the slope of the blue line is 1/2
So y=1/2x+2
Slope is rise/run (up then ((right)))
And the intercept is found where the line intercects the y line.

Answer:
30°, 150°
Step-by-step explanation:
You know the answer to this because you have memorized the short table of trig function values.
sin(θ) = 1/2 for θ = 30° and θ = 150°
