Write the equation of a line with a undefined slope?

1.x=-5
2.y=-5
3.x=-5+3

Option 1

Step-by-step explanation:

A equation of a line with an undefined slope will be graphed as a vertical line.

I used a graphing tool to graph the given options.

Option three will not graph for some reason.

The red line is option 1.

The blue line is option 2.

Remember: A equation of a line with an undefined slope will be graphed as a vertical line.

On the graph, the red line is vertical. The equation for that line is , or option one.

Therefore, option 1 should be the correct answer.

answer: c is correct, a regular pentagon
