I need help please and thank you

C y =1/6x-2

Step-by-step explanation:

We know the y intercept ( value when x =0 ) is -2

That eliminates answer A

We can find the slope

m = (y2-y1)/ (x2-x1)

   = (0 - -1)/(12 -6)

    ( 0+1) / 6

   = 1/6

The slope is 1/6

y = mx+b where m is the slope and b is the y intercept

y =1/6x-2

C

Step-by-step explanation:

f(X)=X/6 -2.

By observation the graph cuts the y-axis when x=0 at y=-2; this explains the last term in the equation.

However two expression has both term by substiting X =-6 in equation b and C

We see that b evaluates to y= -1; while C evaluates to -3 which parallels to the value of Out in the graph hence the answer is C

From B substituting X =-6

-(-6)/6 - 2 = 6/6 - 2 =1-2 =-1

From C substituting X = -6

-6/6. - 2 = -1 -2 =-3

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
