Find an equation of the line passing through the origin and parallel to the line passing through the points (2,8) and (4,12

1st determine slope ("m"):  (y2-y1)/(x2-x1) = (12-8)/(4-2) = 4/2 = 2; thus m=2

2nd determine the "b" value by using slope from above and point (0,0):  y=mx+b; 0=2*0+b; thus, b=0

3rd write the equation: y=2x
