Graphs are hard: The correct one
Which of the 3 points below does not lie on the line \( \dfrac x2 - \dfrac y3 = 5\).
\((-2, -18), (3, -10.5), (7, -5.5)\)
Note: If you do not have graph paper I'd advise you print some out. However, there is an easier way to do it, which does not require graph paper.
