Answer
a) slope: a $0.3$ inch stretch for each pound of increase in weight.
s-intercept: unstretched spring length
b) $4$ inches
Work Step by Step
a) The slope represents a $0.3$ inch stretch for each pound of increase in weight. The $s$ intercept is the unstretched spring length.
b) Plugging in $w=5$, we get: $s=0.3(5)+2.5=4$ in.
