Hi again Ge Manni;
y=52x
I prefer to write this as...
y=2x+5
This is in the format of...
y=mx+b
m is the slope. The slope is defined as the changeofy divided by the changeofx, also known as riseoverrun. 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 yaxis two units, as it moves to the left, the negative direction of the xaxis, one unit.
b is the yintercept. This is the value of y when x=0. One coordinate of this line is (0,5). This line passes through the yaxis at the point of 5 on the yaxis.
