where x represents height and y represents shoe size, to because a man who is -17.52 inches tall does not
predict the approximate height of a man who wears a
make any sense. what was ramona's mistake?
size 8.5 shoe
she substituted the 8.5 for the wrong variable.
1. y = 444(8.5) - 21.29
she should have added 444 and 8.5.
2 y = 3.774 - 21.29
the value for y should be positive.
3 y=-17.52
the solution of -17.52 should be the shoe size
