1. Make y the subject of the equation
y = -4 - 6x


2. Substitute values for guess and check
8 = -4 - (6 x 2)
8 = -4 - 12
This is incorrect.

2 = -4 - (6 x 1)
2 = -4 -6
This is incorrect.

-10 = -4 - (6 x 1)
-10 = -4 -6
This is correct.

The correct answer is C.

ivanzaharov [21]

Answer:

Option C

Step-by-step explanation:

-x/6 ≤ 3

6(-x/6) ≤ 3 × 6

-x ≤ 18

-1(-x) ≤ -1(18)

x ≥ -18

So the line starts from -18 and extends infinitely to the right.
