Question

line equations from point/slope
question
what is the equation of the line that passes through the point (3, -4) and has an undefined slope?
answer
attempt 1 out of 2

Explanation:

Step1: Recall slope types

Undefined slope means vertical line.

Step2: Vertical line equation

Vertical lines have equation \( x = a \), where \( a \) is the x - coordinate of any point on the line.

Step3: Substitute point

The point is \( (3, - 4) \), so \( a = 3 \). Thus, the equation is \( x = 3 \).

Answer:

\( x = 3 \)
