Please help me with this homework

B) y+1=3(x-1)

Step-by-step explanation:

One of the points is (1,-1), and the slope is 3.

The point slope equation is where m is the slope.

It would then be y+1=3(x-1), which is B)

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

won't that be plagrisim thought?
