Question

What is the equation of a vertical line that passes through the point (3, -10)?

Question 1 options:
x = 3
x = -3
x = 10
x = -10

Answer 1

Answer: Choose the equation of the vertical line passing through the point (-2, 3). A vertical line goes up and down through point (-2, 3), so every point on the line will have the same x coordinate. For example, (-2, 0) and (-2, 1) and (-2, -1) all fall on that vertical line. Therefore, the equation for the line is x = -2 Choose the equation of the horizontal line that passes through the point (-5, 1). A horizontal line goes left and right through point (-5, 1), so every point on the line will have the same y coordinate. For example, (-1, 1) and (0, 1) and (1, 1) all fall on that horizontal line. Therefore, the equation for the line is y = 1.

Explanation:

Answer 2

x = 3

Explanation:

The coordinate point is in the format (x, y)

Therefore, the x-value of (3, -10) is 3

So the equation of the vertical line is therefore x = 3
