This gives:



<em>(-2,8) is a point on the grid</em>

This gives:



<em>(7,5) is a point on the grid</em>

This gives:



<em>(-5,5) is a not point on the grid</em>
<em></em>

This gives:



<em>(1,3) is a not point on the grid</em>

This gives:



(1,7) is a point on the grid
So, we plot the following on the grid
