For
each
of
the
parts
below,
use
the
scatter
plot
to
draw
a
line
of
best
fit.
Pick
two
points
on
the
line
and
write
the
equation
of
the
line

Use
StatKey
to
find
the
equation

the
regression
line
and
draw
the
regression

the
value
of
the
residuals
and
add
them
to
the
table.

passed
for
500
yards
in
one
game
but
the
team
somehow
didn’t
manage
to
score
a

How
would
this
