Answer:
Slope: 
Y-intercept: 399
Slope-intercept form: 
Step-by-step explanation:
1. The equation in Standard form is given in the problem:

2. Then, to write the equation of the line in slope-intercept form
, where <em>m</em> is the slope and <em>b</em> is the y-intercept, you must solve for <em>y</em> as you can see below:

3. Therefore, the slope and the y-intercept are:

If tan (x)+pi/6=0
thn
tan (x)=-pi/6
take atan of both sides
x=atan (-pi/6)
x= -0.4823 rad
= -27.636 deg
