Write the equation in point-slope form for the line that contains the points (-2, -3), (4,3)
y + 3 = 1(x + 2)
y -3 = -1(x + 2)
y + 3 = -1(x - 2)
y - 3 = 1(x - 2)

-2 is the right

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
