Answer:
A line parallel to the line y = x -4 would have a slope of 1.
A line perpendicular to the line y = x -4 would have a slope of -1.
Remember, parallel lines are lines that never intersect, which means that they cannot possibly have different slopes. A perpendicular line will <em>always</em> have the opposite slope as the first line, because the two lines must intersect at a 90 degree angle. The attached image shows how this works.

Answer:
Step-by-step explanation:
5. angle FDE = 180-90-63 = 27°
arc FE = 2×27 = 54°
6. arc GJ = 360-68-31-115 = 146°
angle GHJ = 146/2 = 73°
7. angle GIJ = 146/2 = 73°
8. arc DAB = 2×101 = 202°
arc BCD = 360°-202 = 158°
angle A = 158/2 = 79°
angle B = 360-79-110-68 = 112°
