Answer:

A

Step-by-step explanation:

x² - 6x = 8

Using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 3)x + 9 = 8 + 9

(x - 3)² = 17 → A

Answer:

6

Step-by-step explanation:

We need to find the slope

We have 2 points

(0,0) and (1,6)

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

   = (6-0)/(1-0)

   = 6/1

  = 6

y = 6x

The constant of proportionality is 6
