Observations when Visualising Linear Relationships After observing the graphs, we may conclude the following: Slope and y-intercept For any line y = ax + b, a is the slope b is the y-intercept Changing value of a, keeping b fixed If we change the values of a, keeping b fixed, the slope of the line changes while the y-intercept remains fixed. Changing value of b, keeping a fixed If we change the values of b keeping the value of a fixed, the lines shift but remain parallel to the original line. Thus, lines with equal slopes but different y-intercepts are parallel to each other.
