Line shifted vertically based on value of the offset.
The offset is calculated by rearranging the original equation to solve for the offset and then using
known values for the other variables to solve for the offset. The known values can come from
any single point on the graph, for example Y2 and X2, but not Y2 and X1as they are from
different point on the graph. The offset will not change the angle or slope of the line but
vertically shifts the line based on the value of the offset.
