a=1

you run before you jump, and 7-8 is 1   the it is like saying 
   x 0
  0 x  there is one space in between the 0's

easy, since the y coordinat didn't change, y didn't move
only x moved
we just see how far x moved
-8 to -7
that is 1 distance

or ou could use distance formula

the distance between the points
(x1,y1) ad (x2,y2) is
D=[tex] \sqrt{(x2-x1)^{2}+(y2-y1)^{2}} [/tex]
points are
(-8,-2) and (-7,-2)
D=[tex] \sqrt{(-7-(-8))^{2}+(-2-(-2))^{2}} [/tex]
D=[tex] \sqrt{(1)^{2}+(0)^{2}} [/tex]
D=[tex] \sqrt{1+0} [/tex]
D=[tex] \sqrt{1} [/tex]
D=1
