Step-by-step explanation:
vector u=<(11-(-7),(-5-2)>=<18,-7>

so vector v=-3(18,-7)=(-54,21)
Answer:
The slope of line representing Luigi's numbers from 30 seconds to 60 seconds is
Step-by-step explanation:
At 30 seconds, he collected 14 coins
At 60 seconds, he collected 55 coins
time difference, Δt = 60 - 30
⇒ Δt = 30 seconds
additional coins collected in this time, Δc = 55 - 14
⇒ Δc = 41 coins
Now, slope of the line = Δc/Δt =
<u>∴ The slope of line representing Luigi's numbers from 30 seconds to 60 seconds is coins/sec</u>
