This is a horizontal line, 5 units below the x-axis (at y = -5). Since y = -5 for all x, adding 5 will give zero.

The equation you are looking for is x + 5 = 0. To solve for x, you would subtract 5 from both sides of the equation. This would give you x = -5. Therefore, -5 plus 5 equals 0.
You can simplify the equation by dividing by 5 and solving for y giving you y=-x-5. If you were to graph it the slope would be -1, the y-intercept would be (0,-5), and the x=intercept would be (-5,0).
All those where y is 9 more than x will be included on the graph of y = 9 + x.eg (0, 9), (1, 10), (-5, 4).
