Answer:
Lorena made a mistake when she subtracted x1 from x2
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
In this problem we have
The points are
and 
therefore
Lorena made a mistake when she subtracted x1 from x2
There are two solutions for this problem. It depends if order matters or not. As asked in the problem, we have to show both solutions.
The first solution is for the condition that order does not matter. This is a combination problem:
nCr = n!/r!(n-r)!
where n=10 because there are 10 total students, and r=2 because you choose 2 students at a time
nCr = 10!/2!(10-2)! = 45 ways
The second solution is for the condition that order matters. This is a permutation problem.
nPr = n!/(n-r)! = 10!/(10-2)! = 90 ways
Answer:
-1/3
Step-by-step explanation:
the equatio is set up y=mx+b and m is you slope(1/3). So you have to move mx(1/3 x) to the other side. You do this by subtracting so, your slope becomes -1/3
