On the Cartesian plane, the line y = 0 is called the:

y-axis.
x-axis.
Origin.
The sum of the three interior angles of a triangle is:
270°.
360°.
180°.
90°.
The midpoint of the line segment joining the points P(6, - 3) and Q(18, 15) is the point with coordinates:
(- 6, - 9).
(12 ,6).
(- 6, 6).
(12, 12).
A triangle ABC with vertices A (2, 5), B (5, - 2) and C (0, -1) is reflected along the y-axis to give the image triangle A/B/C/.
The coordinates of the vertices of A/B/C/ are:
A/(-2, 5) , B/(5,2) , C/(0, 1).
A/(-2, 5) , B/(-5,-2) , C/(0, -1).
A/(2, 5) , B/(-5,2) , C/(0, 1).
A/(-2, 5) , B/(-5,2) , C/(0, 1).
