<u>As per the graph we have:</u>
- Coordinates of JL are J(-7, 4), L(-4, 0)
- Coordinates of MP are M(-10, 8), P(-1, -4)
<u>Slope formula is:</u>
<u>Slope of JL:</u>
- (0 - 4)/(-4-(-7)) = - 4 / 3
<u>Slope of MP:</u>
- (-4 -8)/(-1- (-10)) = -12 / 9 = - 4/3
Answer:
The answer is 720 ways.
Step-by-step explanation:
Total friends who volunteered = 10
Total number of jobs that have to be done = 3
Here order matters, so it is a permutation question.
We can use the formula nPr.
= 
= 720 ways.
The second way to solve this is:
Susan can choose the first person to do a job in 10 ways
Then the second job can be done in 9 ways and the third in 8 ways.
Total becomes =
ways
