Option C:
It is throughout the line.
Solution:
Point on the larger shaded triangle are (0, 0) and (–6, –2).
Point on the smaller shaded triangle are (–6, –2) and (–9, –3).
Slope of the line:
Slope of the larger triangle:
Here,
Slope of the smaller triangle:
Here,
Both slopes are equal.
It is throughout the line.
Hence option B is the correct answer.
