(3, -7) and (-1, 1)
To find slope of a line using 2 points
we use formula
(3, -7) is (x1,y1) and (-1, 1) is (x2,y2)
Here x1= 3 and y1= -7
x2=-1 and y2=1
=-2
slope of a line using 2 points (3, -7) and (-1, 1) is -2
No 87.64 is the correct answer
Answer:
If the positions are distinct, as in executive offices, then P(9,5)
P(9,5) = 9!/(9 - 5)! = 15120..... is the answer
But...
If the positions are equivalent, such as seats in a legislative body, then C(9,5)
C(9,5) = 9!/[(9 - 5)!(5!)] = 126
Hope this can help you :)
In the picture we can see one whole square and 1/4 of a whole square shaded this means that 1 1/4 or 5/4 would be appropriate answers but it says that you are trying to find a appropriate mixed number. A mixed number is a number that includes a whole number and a fraction. For example, 3 1/3 is a mixed number. This means that it can't be 5/4 because it doesn't include a whole number leaving 1 1/4. So, 1 1/4 or D would be correct.
