Answer

a) Please see the graph. b) $(5,66.5)$ c) The ordered pair means that, in 2003, 66.5 percent of households had computers.

Work Step by Step

a) Let $x=0$ $y=5.6x+38.5$ $y=5.6*0+38.5$ $y=38.5$ Let $x=1$ $y=5.6x+38.5$ $y=5.6*1+38.5$ $y=5.6+38.5$ $y=44.1$ Let $x=2$ $y=5.6x+38.5$ $y=5.6*2+38.5$ $y=11.2+38.5$ $y=49.7$ Three points on the line are $(0, 38.5), (1,44.1),$ and $(2,49.7)$. b) $y=5.6x+38.5$ $y=5.6*5+38.5$ $y=28+38.5$ $y=66.5$
