Since both lines c and b are perpendicular to line a, line c and b are parallel.
Using the two points on line b, we can count “up 5, right 5” to find the slope of line b to be 5/5 or 1.
Since line b has a slope of 1 and line c is parallel, it must also have a slope of 1.
Answer:
622,080
Step-by-step explanation:
The total number of subjects is 3
= 3×2×1
= 6
Six maths book
= 6×5×4×3×2×1
= 720
Four physics book
= 4×3×2×1
= 24
Three chemistry book
= 3×2×1
= 6
6×720×24×6
= 622,080
Hence if the books are grouped together 622,080 arrangement is possible
