Question

Find the inclination θ (in radians AND degrees) of the line:

4x-2y-4=0

Answer 1

you got the slope?

Answer 2

no

Answer 3

put it like y=mx+c

Answer 4

-2y=-4x+4 ---->y=2x-2

Answer 5

slope=2 then

Answer 6

ok then what?

Answer 7

slope=tan theta...theta=tan inverse(2)

Answer 8

then since \(\tan(\theta)=2\) you can find \(\theta\) via \(\theta =\tan^{-1}(2)\) with a calculator

Answer 9

63.43 degrees
