The equation of the line of best fit relating age (in years) and the median height (in cm) of boys is given. y
=
6.5
x
+
75.5
y=6.5x+75.5
Which statement below best interprets the slope in the context of the problem?

The slope is 6.5, this means that the median height for boys at age 0 is 6.5 cm.

The slope is 75.5, this means that the median height for boys at age 0 is about 75.5 cm.

The slope is 75.5, this means that each boys grow approximately 75.5 cm.

The slope is 6.5, this means that each year boys grow approximately 6.5 cm.
