Question

Select the equation of the line that passes through the point (5,7) and is perpendicular to the line x=4A) y=4B) x=5C) y=7D) x=7

Answer 1

Answer: C) y = 7

Step-by-step explanation

Perpendicular lines are those that form a 90º angle. Additionally, x = 4, is a vertical line, thus, we have to find the corresponding horizontal line that passes through a point (5, 7).

As the coordinate is (x, y), and we need a horizontal line (y = a), then:

`y=7`
