Answer:  C) y = -3x + 1

Step-by-step explanation:

     x          y  

   -2          7

    2         -5

    4         -11

    6         -17

    10       -29

Choose any two coordinates to find the slope: [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

m = -6/2

   = -3

Choose any point and plug it into the Point-Slope formula:  [tex]y-y_1=m(x-x_1)[/tex]  

y - 7 = -3(x  + 2)

y - 7 = -3x - 6

y      = -3x + 1
