Question

How do you graph `x + 7= 0`?

Answer 1

A vertical line going up at -7

Explanation:

First solve for x by subtracting 7 from both sides

`x + 7 -7 = 0 -7` This gives

`x = -7`

This is true for all values of y. so (-7, 0) (-7,1) ( -7, -1) are all on the line.

This results in a vertical line at `x=-7`
