assuming you can't repeat a person (duplicates?)

in the 1st chair, there are 5 possible people you can put there

in the 2nd chair, there are 4 possible people you can put there since 1 person already has a chair

in the 3rd chair, there are 3 possible people you can put there since 2 people already have chairs

so there are 5*4*3 or 60 ways to arrange 6 people in 3 seats

Find the gradient of the line passing through (6,8) and (4,10)

Mariulka [41]

Question:

Find the gradient of the line passing through (6,8) and (4,10).

Answer:

-1 is the right answer.

Step-by-step explanation:

Slope of the line = The gradient of the line

Gradient of the line is known as change in the value of y-axis by change in the value of x-axis

Gradient = ∆y\∆x

$Gradient = \frac{y_ 2 - y_1}{x_2 - x_1} = \frac{(10 - 8)}{(4 - 6)} = \frac{(2)}{(- 2)} =\boxed{- 1}\\$
