Luka pente ya ligne entre (-2,4) na (4,-4).
 Pente ya ligne kati ya ba points mibale (x1, y1) na (x2, y2) elimbolami lokola mbongwana ya y ekabolami na mbongwana ya x. Na matematiki, pente = (y2 - y1) / (x2 - x1) Na boye, pona ba points (-2,4) pe (4,-4), pente = (-4 - 4) / (4 - (-2) . ) = -8 / 6 = -4/3 Bopanzani ya ligne kati ya (-2,4) na (4,-4) ezali -4/3.
