The graph of
... y = 3/4 - 2
is a horizontal line at y = -1.25.
The graph of
... y = (3/4)x - 2
is an upward-sloping line with a rise of 3 for every 4 units to the right. It intercepts the y-axis at y = -2.
If the relationship between two quantities is a proportional relationship, this relationship can be represented by the graph of a straight line through the origin with a slope equal to the unit rate.
