Let X be the pounds & Y be the time to cook.
(4,100) (10,230)
Y=mX+b
m=slope=(Y2-Y1)/(X2-X1)
m=(230-100)/(10-4)=130/6=21.667 is the slope.
100=21.667*4+b
100=86.667+b
b=100-86.667
b=13.333 is the Y intercept.
Y=21.667x+13.333
(graph 300x200 pixels, x from -6 to 15, y from -100 to 250, 21.667x +13.333).
