Hi

Using the point-slope formula, m+=%28y%5B2%5D+-+y%5B1%5D%29%2F%28x%5B2%5D+-+x%5B1%5D%29

 (3,3), (0,-3)

  m = ( -3 - 3 )/ (0 - 3) = -6/-3 = 2

  m = 2  therefore, as y increases/decreases by 2, x increases/decreases by 1

(3,3), (2, n)  n = 1  (x decreased by 1,therefore y must decrease by 2)

OR given Pt(0,-3) and m = 2,  y = 2x -3, Pt(2, n) n = 2*2-3 = 1
