30×6=180
Answer: 2i
Step-by-step explanation:
When a line is reflected along the x axis, the sign of the x coordinate of the points on the line remains the same while that of the y coordinate is reversed. Therefore,
For point A, the x coordinate is - 2 and the y coordinate is - 1. After relection over the x axis, it becomes
(- 2, - -1)
= (- 2, 1)
For point B, the x coordinate is - 1 and the y coordinate is - 3. After relection over the x axis, it becomes
(- 1, - -3)
= (- 1, 3)
The coordinates after reflection are A(- 2, 1), B(- 1, 3)
