Question

Determine the slope and equation of a line passing through the point (2, -1) and parallel to the y-axis.

Answer 1

Answer:

x=2 would be the equation.

Step-by-step explanation:

Let's take any two points from y-axis. Like (0,4) and (0,5)

Now,

Slope (m) = (5-4)/(0-0)

= 1/0

this is undefined.

slope of parallel lines are same, so the slope of (2,-1) is also 1/0 which is undefined.

Since its undefined equation would be x = 2
