Question

Write an equation for the line on the graph below:

Answer 1

x=-1

It's a vertical line so it touches all y's. The only x it touches is -1.

Answer 2

The equation would be x = -1

Explanation:

Since the line is vertical, all y = all real numbers. This means that only x needs to be addressed, and since every x value is equal to -1, that's what the equation would be.
