Slope is the steepness of a line.
It is expressed as rise / run.
The rising axis is the Y axis and the running axis is the x-axis.
The formula for slope is

From above we have two coordinates. All coordinates are in (x,y) from
Our first coordinate is (X1,Y1) = (6,6)
Our second coordinate is (X2,Y2) = (2,2)
From these we get

The slope of the line between two points represents the change in the y-coordinates divided by the change in the x-coordinates. This is sometimes called the rise (of the line) over the run (of the line).
In general the slope between two points (x1,y1) and (x2,y2) is then
(y2-y1)/(x2-x1)
So for these points the slope is (6-2)/(6-2) = 4/4 = 1
One of the standard forms of a line called the slope-intercept form:
y = m*x + b
In this form of a line m represents the slope and b represents the value of y where the line crosses the y-axis (which is when x = 0).
In this particular case we already calculated the slope m to be 1 so the equation of the line is:
y = 1*x + b
We still need to find b. Since the line passes through the point (2,2) we know that when x=2, y is also equal to 2.
So substituting 2 for x and 2 for y in the equation above:
2 = 1*2 + b
2 = 2 + b
b = 0
The equation for the line in slope-intercept form is:
y = 1*x + 0 or
y = x
