His number line is incorrect, or he plotted the point incorrectly. We know that the numbers on a number line get bigger as we get farther and farther away from zero on both sides. So -4 being closer to zero than -2 is impossible on a perfect number line. Thus, he either needs to check his counting, or check if he plotted the right number.

Complementary angles: two angles that add to 90°
Supplementary angles: two angles that add to 180° (x)
angle "y" : y= 5x+6
180= (5x+6) + x
180=6x+ 6
174=6x
x=29
180- 29= 151
Answer: 151°
