Find the slope of the line that passes through (81, -18) and (7, -56).

Slope (m) =

ΔY

ΔX

=

38

79

=

0.48101265822785

θ =  

arctan(

ΔY

) + 180°

ΔX

=

205.68814343565°

ΔX = 7 – 86 = -79

ΔY = -56 – -18 = -38

Distance (d) = √ΔX2 + ΔY2 = √7685 = 87.664131775772

Equation of the line:

y = 0.48101265822785x – 59.367088607595

or

y =  

38

x

79

–  

4690

When x=0, y = -59.367088607595

When y=0, x = 123.42105263158

19/37

Step-by-step explanation:

(-18-(-56))/(81-7)

38/74

19/37

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

plz mark brainliest i took the test
