Please help me with this math problem

E.  y = 2/3x

Step-by-step explanation:

You need to make an equation in slope-intercept form.  

First, you need to find the slope.  You can do this by taking two points and dividing the difference of the y's by the difference of the x's.  I will use the first two points, but you can pick whichever points you want and still get the right answer.  Also, the values in the left column will be x's, and the values in the right column will be y's.

8 - 2 = 6

12 - 3 = 9

6/9 = 2/3

The slope is 2/3.  The only equation with this value is E.

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8  

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.
