Question 982117
<pre>
The first tutor gave one possible solution, but there are infinitely many possible answers.

(-1.5,5), (-1.5,7), (-1.5,0), (-1.5,100), (-1.5,-100), etc.

the x-coordinate can only be -1.5, but the y-coordinate can be any number
except the two values that produce an equilateral triangle, since there are
no non-congruent sides to an equilateral triangle.  Here are 4 solutions.
The last one is the one the first tutor gave.
