What is the value of k if a line passes through (6,3) and (2,k) has a slope of -1?

k = 7

Step-by-step explanation:

Slope =

-1 =

Multiplying both sides by 2-6

-1(2-6) = k-3

-1(-4) = k-3

4 = k-3

Adding 3 to both sides

k = 4+3

k = 7

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.

hope this < 3

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
