Hi again Ge Manni;
Let's first consider...
This is one third of 3/5...
The slope of this line is 1/5. Slope is defined as the change-of-y divided by the change-of-x, also known as rise-over-run. This line rises one unit as it moves to the right five units.
The equation is in the format of...
m is the slope.
b is the y-intercept, the value of y when x=0.
One coordinate of this line is (0,0). This line passes through the y-axis at the point that the y-axis intersects the x-axis.
