parallel means same slope

using point-slope; y-1=(5/2)(x-2)

Y=5X/2+6 (RED LINE) HAS A SLOPE OF 5/2 SO ANY PARALLEL LINE ALSO HAS A SLOPE OF 5/2.
THUS PASSINGH THROUGH (2,1) WE NEED TO SUBSTITUTE THESE VALUES IN THE LINE EQUATION Y=mX+b & SOLVE FOR b
1=5/2*2+b
b=1-5
b=-4 SO THE PARALLEL LINE EQUATION IS;
Y=5X/2-4 (GREEN LINE)
