m = 6/3 =2

Explanation:

Slope means the steepness or gradient of a line.

It can be described as the " "("change in the y-values")/("change in the x-values")

which is sometimes explained as ("rise")/("run")

The formula is m = (y_2-y_1)/(x_2-x_1)

The points are (2,2)" as (x_1,y_1)" and " (5,8) as (x_2,y_2)

m = (8-2)/(5-2) = 6/3 = 2

m=2

Explanation:

The slope formula determines a slope from two points.

It says that given two points (x_1,y_1) and (x_2,y_2), you find the slope from:

m=(y_2-y_1)/(x_2-x_1)

If we let (2,2)=(x_1,y_1) and (5,8)=(x_2,y_2), then we can plug these values into the slope formula.

Note that it does not matter which of the two points you decide to be the "first" or the "second".

m=(8-2)/(5-2)=6/3=2
