General nomenclature of linear equations is
y=mx+b where m is the gradient (or slope) while b is the y-intercept.
Depending on the value given, b can cross the y axis at any point.
Say
y=-3/8x .... meaning b=0
y=-3/8x+1 .... meaning b=1
and so forth. So, it depends on the values given or rather the cordinates given.
