If theta is in standard position and the terminal side of theta is in the quadrant III and on the line 4x-3y=0, find the exact value of sin theta.

Question

phi · Answer

did you plot the line 4x-3y=0 ?  
First put it in slope-intercept form.

anonymous · Answer

no!

anonymous · Answer

the slope is 4/3

phi · Answer

slope intercept form is y= mx+b
start with 4x-3y=0
add 3y to both sides to get
4x= 3y
divide both sides by 3
(4/3) x = y
or, 
y= (4/3) x

can you plot this line?

anonymous · Answer

I got that! I have the graph drawn.
