Answer:
x + 1 = -5 is a vertical line, with an undefined slope.
Explanation:
Given the equation of the line, x + 1 = -5:
You can start by subtracting 1 from both sides of the equation to isolate x:
x + 1 - 1 = -5 - 1
x = -6
This is an example of a vertical line with an undefined slope, and an x-intercept of (-6, 0). The x-intercept is the point in the graph where the line crosses the x-axis; it is also the value of x when y = 0.
Since this is a vertical line, you can start with the x-intercept, (-6, 0), and draw a straight vertical line from there. You can choose any y-coordinate, as long as the x-coordinate is always -6.
For example, in the attached image I created the graph by choosing some points. I started at (-6, 0) (the blue dot on the screenshot), then I also plotted the following points: (-6, -10) (-6, -5) (-6, 5) (-6, 10) (-6, 15). Then, I connected the points, creating the line for the equation, x + 1 = -5. As you can see from the given points, the y-coordinate changes, but the x-coordinate of these points are the same (-6).
