Question

Find the equation of the line whose y-intercept is 5units and inclination is 150°​

Answer 1

Answer:

x+root3 y-5 root3=0

Explanation:

by slope intercept form,

y=mx+c

where c=5

and m=tan 150°

and tan 150=-1/root3

therefore,

y=mx+c

y= -1/root3 x+5

root3 y= -x+5 root3

x+root3 y-5 root3=0
