Hi again Ge Manni;
I prefer to write this as...
This is in the format of...
m is the slope.  The slope is defined as the change-of-y divided by the change-of-x, also known as rise-over-run.  The slope of this line is -2, -2/1.  The protocol of mathematics requires that the negative sign is in the numerator.  However, the field of mathematics is contradicting itself.  The way a negative line functions is with the negative activity occurring in the denominator, 2/-1.  This line rises positively on the y-axis two units, as it moves to the left, the negative direction of the x-axis, one unit.
b is the y-intercept.  This is the value of y when x=0.  One coordinate of this line is (0,5).  This line passes through the y-axis at the point of 5 on the y-axis.
