$y=\dfrac{-x-6}{2}\qquad\text{multiply both sides by 2}\\\\2y=-x-6\qquad\text{subtract 2y from both sides}\\\\0=-x-2y-6\\\\\boxed{-x-2y-6=0}\qquad\text{change the signs}\\\\\boxed{x+2y+6=0}$

If it helps, use desmos to help graph so you can get more accurate results.

Just search up www.desmos.com/calculator and the way you insert your numbers is by example: (1,2) and you'll see a dot appear on the graph. You start a another line by clicking below and entering your next pair of coordinates.

Hope this helps! c:

Graph on the number line all values of x that satisfy 2x+2/x+7 >= 0

LiRa [457]

All values of x that satisfy 2x+2/x+7 >= 0 are represented as x >= -1

<h3>How to graph the inequality on a number line?</h3>

The inequality expression is given as:

2x+2/x+7 >= 0

Multiply both sides by x + y

2x+2 >= 0

Subtract 2 from both sides

2x > -2

Divide both sides by 2

x >= -1

Hence, all values of x that satisfy 2x+2/x+7 >= 0 are represented as x >= -1

See attachment for the number line of x >= -1
