Step-by-step explanation:
The slopes of lines can be used to define the nature of lines.
Two parallel lines have equal slopes and the product of slopes of perpendicular lines is -1.
Hence, we can conclude that two distinct non-vertical lines parallel when

Answer:
3 years -> value decreases by 20% 3 times
20% -> value is 80% of the original price
1st year value (after 20% decrease) = S15,500×
= S12,400
2nd year value (after 20% decrease) = S12,400×
= S9,920
3rd year value (after 20% decrease) = S9,920×
= S7,936
