Question

How do you find a standard form equation for the line with x-intercept (–2, 0) and undefined slope?

Answer 1

`x+2=0.`

Explanation:

Undefined slope means the line must be vertical, i.e., parallel to Y-Axis. and it passes thro. a pt. `(-2,0)`

Now, the eqn. of a vertical line thro. pt. `(a,b)` is `x=a.`

In view of above, the reqd. eqn. is `x=-2,` or, `x=2=0.`
