You would move the point up or down one (this is because you are moving on the y-axis) which would only change y leaving x alone as -3. This means you would either subtract 3 or add 3 to 4 which gives you 1 or 7.
<span>The biggest number of groups that can be formed is 6, because six is the greatest common factor of 12 and 42. There will be 2 coaches in each group because 6 x 2 = 12 and 7 players in each group because 7 x 6 = 42.</span>
