Choose the equation below that represents the line that passes through the point ( -2, -1) it is a sslope of 5. a. y+2=5(x+1). b. y+1=5(x+2) c. y-1=5(x+2). d. y-2=5(x-2)

point slope form

y -y1 = m(x-x1)

y- -1 =5(x--2)

y+1 =5(x+2)

Choice B

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
