Check a candidate point against two lines
The two lines and one candidate point are shown below
\[\ell_1: y=-2x-\frac{7}{3}\]
\[\ell_2: y=-\frac{11}{3}x+\frac{5}{3}\]
The candidate point is \(P(\frac{1}{3}, -3)\)
The two lines and one candidate point are shown below
The candidate point is \(P(\frac{1}{3}, -3)\)
