How do you find the rate of change using a graph?

answer:

the correct answer is the vertical change divided by the horizontal change between two points on a line. we can find the slope of a line on a graph by counting off the rise and the run between two points. if a line rises 4 units for every 1 unit that it runs, the slope is 4 divided by 1, or 4.

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
