Answer
see below
Work Step by Step
$(0, 0)$; $(4, 2)$
(a) The distance between the points
= $\sqrt {4^2 + 2^2}$ = $2\sqrt5$
(b) The midpoint of the line segment connecting the points
$(\frac{4+0}{2}, \frac{2+0}{2})$ = $(2, 1)$
(c) The slope of the line containing the points
= $\frac{2-0}{4-0}$ = 0.5
(d) Interpret the slope found in part (c)
Positive slope, with value less than 1 i.e 0.5
Which implies, x increase twice as much as y
