Question

Write the equation of a vertical line that passes through the point (3, –3).

x = – 3
y = 3
y = – 3
x = 3

Answer 1

`x = 3`

EXPLANATION

The equation of a vertical line that passes through

`(x_1,y_1)`

is given by

`x = x_1`

That is x equals the x-value of the point.

Since the vertical line passes through (3,-3).

Therefore the equation of a vertical line that passes through the point (3, –3).

`x = 3`

Answer 2

Answer: last option.

Explanation:

We know that the line is vertical and it passes through the point (3, -3).

Then, since it is vertical, the equation of this line will have the following form:

`x = a`

Where "a" is the value of the x-coordinate (Because vertical lines passes through all points with the same x-coordinate)

Then, you can observe in the given point that the x-coordinate is 3. Therefore, the equation of the line is:

`x=3`
