Figure shows line n in a rectangular coordinate system. An equation of line n is

Options

A. x = 4
B. y = 4
C. x = 5
D. `y=(5)/(4)x`

Answer

A

Explanation

Since line n is perpendicular to the x-axis, and the y - axis is perpendicular to the x - axis, line n is parallel to the y - axis, and every point on line n has the same x - coordinate. You know that one point on line n has the coordinates (4, 5). The x - coordinate of this point is 4. So the x - coordination of every point on line n is 4. The equation of line n is x = 4.
