Can someone me with 1,2,4 show me how to do it

I only know what the answer is to number four.

For numbers 1 and 2 just line the points up over the fraction bar,

8-2. 6

—— = — M =6

6-5. 1

For number 4 the slope is 3

- —

4

The number right in front of the x.

Hope I helped ^u^

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

whats the question?
