Which equation does the graph below represent?

y = 2x
y = 1/2x
y = 1/2 + x
y = 2 + x

B

Step-by-step explanation:

Choose any point and put it into one of the choices of equations. Let's just do (4, 2):

A) y = 2x  ⇒  2 =? 2 * 4  ⇒  2 ≠ 8   ---   eliminate

B) y =1/2x  ⇒  2 =? 4 * (1/2)  ⇒  2 = 2   ---   correct; keep it

C) y = 1/2 + x  ⇒  2 =? 1/2 + 4  ⇒  2 ≠ 4.5   ---   eliminate

D) y = 2 + x  ⇒  2 =? 2 + 4  ⇒  2 ≠ 6   ---   eliminate

Thus, B is the correct answer.

Hope this helps!

y = ½x

Step-by-step explanation:

Using (4,2) and (0,0)

y-intercept is 0

Slope: (2-0)/(4-0)

2/4 = 1/2

y = ½x + 0

y = ½x

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
