Which equation is satisfied by all of the plotted points?

a. y = 2x
b. y = x + 3
c. y = 2x + 1
d. y = -2x
e. y = x
f. y = 3x -3

I think the correct answer from the choices listed above is option D. The equation that would satisfy all of the points plotted above would be y=-2x. From the plot, we can see that the y-intercept is equal to zero and by using two points we can calculate the slope to be equal to -2. Giving an equation which is y=-2x. 

The answer is 10. and if you go by pemdas you would 1. multiplication 2. division 3. addition 4. subtraction
