What is the slope of (2,-2) and (5, -6) ?

m = - 4 /3

Step-by-step explanation:

Slope is essentially change in height over change in horizontal distance, and is often referred to as "rise over run." It has applications in gradients in geography as well as civil engineering, such as the building of roads. In the case of a road the "rise" is the change in altitude, while the "run" is the difference in distance between two fixed points, as long as the distance for the measurement is not large enough that the earth's curvature should be considered as a factor. The slope is represented mathematically as:

m = y2 - y1 / x2 - x1

m =( -6) - (-2)/ 5 - 2

m = -6 plus 2 / 3               I put plus because negative times negative is plus

m = -4 / 3        negative 6 plus 2 is -4

To find y2, y1, x2 and x1 you have look on the two points that they gave you.

(2, -2), The x1 is 2 and y1 is -2

(5,-6), The x2 is 5 and y2 is -6

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

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
